...details the design and development of a motorized car jack powered the 12 V DC electric outlets available in most modern cars. The motivations behind the project and the objectives and goals of the project are also discussed. Although it was initial plans were to develop a pneumatically operated jack that would work on the car exhaust fumes, rough calculations showed that this idea would not be feasible for safe operation. We later settled on the project idea of a conventional scissor jack that would be operated electrically through the cigarette lighter outlet. Moving further there were two options available – design a scissor jack form the ground up or to retrofit existing jacks with a motor. It was collectively decided to opt for the retrofit. Pros and cons of this are discussed in the report. The report provides comparisons of the various component selections and the reasons behind the selection. The main goal was to find creative ideas to keep costs low and to increase safety margins as high as possible. 1. INTRODUCTION AN automotive jack is a device used to raise all or part of a vehicle in order to facilitate repairs. It is an indispensable tool for any vehicle.owner. Anybody who has owned and driven car for a substantial time has had to use a jack to replace a tire at some point. Most people are familiar with the basic car jack (manually operated) that is still included as standard equipment with most new cars. Not only is it used in case of emergencies such...

...change a tire in no time and get back on the road to finish off your day. The first step is to locate the spare tire and the car jack, every car has a spare tire and jack usually located in the trunk of the car. Once you have taken the spare tire and the jack out the trunk of the car make sure that you are on a good hard surface, you don’t want the jack to sink into the ground. Locate the car frame in which you will place the jack right under it so that it will have a good strong hold of the car. You don’t want to be near the car when the car jack is not holding the frame it can become weak and could fall on you while changing the tire. With the tire iron that is included with the car jack you need to just loosen up the lug nuts before you jack the car up. This step will help you remove the tire easier once it is on the jack. With that being done now you can jack the car up just enough where you can take the flat tire off the car. With the car on the jack and the tire is up enough to take off go ahead remove the lug nuts. Before you place the spare tire on the car make sure that it has good air pressure because the spare tire will be smaller than your regular stock tire. Once you have checked that the tire is in good shape you can place the spare tire back onto the vehicle and screw back on the lug nuts. A good way to make sure that the tire is on the car evenly screw them in a star shape pattern so...

...Up Your Car It is almost certain that at some point you will experience; and have to change a flat tire. The most critical part of the process is jacking the car. However, there is no need to panic. By following a few simple steps before jacking the car, the tire can be safely changed. 1. Position the vehicle in a safe location. A location that is clear of the roadway is ideal. The car should be as for from other moving vehicles as possible. Also select a location that is flat and level, this will help prevent the vehicle from rolling or falling off the jack. In most situations it is ok to drive the vehicle a short distance on the flat tire to find a suitable location. If you must jack the car on the side of the roadway, park on the shoulder and turn the hazard lights on so that others will see you. 2. Before exiting the vehicle. The vehicle’s engine should always be shutoff before jacking. If you have an automatic transmission, place the shift lever in the park position. If your car has a manual transmission, place the shift lever in the reverse position. Next set the parking brake and exit the vehicle. All other passengers should be removed from the vehicle and positioned away from the traffic. 3. Gather all necessary equipment required to jack the vehicle. If you are not familiar with the jacking procedure, retrieve and review the cars owner’s manual. The owner’s manual will show the location of the jack and other equipment required to jack the vehicle...

...LAW CASE STUDY (Topic-2) "The core idea of negligence is that people should exercise reasonable care when they act by taking account of the potential harm that they might foreseeably cause harm to other people.”[1] INTRODUCTION: In this particular case are there many contractual terms that are used. So, to solve this case or before giving any judgement, we need to define these terms and gain sufficient knowledge about them. The first and the most important thing we need to know is: What is a contract? A contract is an agreement which is enforceable by the court of law. For a legal contract there has to be an offer and its acceptance. “Acceptance occurs when the party answering the offer agrees to the offer by way of a statement or an act. Acceptance must be unequivocal and communicated to the offer or the law will not deem a person to have accepted an offer merely because they have not expressly rejected it. Some modifications to the rules of offer and acceptance have been made to protect consumers by sections 18 and 41 of the Competition and Consumer Act 2010 (Cth) schedule 2 Australian Consumer Law (“ACL”) for example, invitations or offers to purchase cannot be misleading or deceptive.[2] Thus acceptance is a very important concept of contracts. Generally a valid contract has acceptance. The different types of contracts are: Formal Contracts and Simple Contracts. “A simple contract can be totally written, partly written and partly “oral” (verbal), or totally oral...

...However, if QVC hadn’t allowed Jack to use the vehicle for private purposes it would be an exempt benefit as this would be used only for work related travel or for infrequent and irregular uses: s8(2) Fringe benefit tax assessment act 1986 (FBTAA). As the car is a fringe benefit we must calculate the car’s fringe benefit tax to do so we can either use the statutory formula method or the operating cost method found in FBTAA 1986 s9 for statutory and s10 for operating. Statutory formula: (($65,000x0.20x184)/365)-$5000=$1553.42 Operating cost method: ($27500x23.6%)-$5000=$1490 The more obvious choice for QVC to choose would be the operating cost method, luckily for them Jack keeps all receipts, invoices etc; as jack has kept these documents QVC can choose the operating cost method, however if they hadn’t kept those documents they wouldn’t have had adequate FBT records. As the employer has provided Jack with the car and Jack hasn’t personally paid any money to obtain the vehicle we will use the type 1 rate when we gross up the tax. $1490x2.0802=$3100.39...

...the brakes on a car Leslie Jenkins DeVry University Professor Hatcher March 11, 2011 How to change the brakes on a car Most people think it is a very tough job to change the brakes on a car. Those people take it to a garage and spend a lot of money in parts and labor to have the job done. Usually it cost anywhere from $90.00 to $215.00 per axle at the garage, per axle means both wheels on the front or rear of the car. By doing the work yourself you could save a lot of money, the only cost is in the parts. The average cost is from $30.00 to $60.00 per axle. Let’s discuss the procedure to change your own brakes. First thing you must do is go to a local car parts store and purchase the correct brake pads for your car. Once you have the brake pads you now can start the remaining process. The next step is to locate a flat, level area to park the car so when you start to jack the car up, it will not roll off the jack. Once you have located the area. To prevent rolling, you need to “chalk” the wheels. This means to put a brick or a large block of wood behind the back tires or front tires depending on which part of the car you need to change the brakes on. Before we can even start to jack up the car we need to loosen the wheel lug nuts. Use a tool called an impact wrench or a breaker bar to loosen the lug nuts. We do not want to remove the lug nuts completely from the car until it is off the ground. If we remove the lug nuts now and start to jack up the car the wheels can...

...HOW TO CHANGE OIL IN A CAR Definition * Friction – This is the resistance an object encounters when its surface is moving over the surface of another object. It generates wear and heat. * Oil filter – this is a device that filters oil to remove contaminants in an engines oil system. Introduction Vehicles are very important in our lives. They ferry us from place to place and they also carry goods for us. But like any other machine they require maintenance, this includes checking and fixing several parts from time to time. Another very important routine maintenance in a car is changing oil. The process of changing oil involves removing the old oil from the vehicle’s engine and adding fresh oil. The reason why changing oil in a vehicle engine is important is because as the engine parts move they rub against each other and create friction which generates heat and wear in the parts. Now the oil in an engine lubricates the moving parts reducing friction and wear and at the same time absorbing the heat generated and hence ensuring that the engine parts work together effectively and efficiently. After a period of time the oil in the engine breaks down and its quality deteriorates, this is due to the dust and other contaminants. Hence the oil is not able to lubricate the engine parts and absorb the heat generated. Therefore if you own a car you need to change the oil before it looses its quality. Changing oil is done often depending on the manufacturers specification. Precautions...

...look at the different scenarios that led to the arrest of Jack after he fled a murder and attempted murder crime scene. Behind each murder or attempted murder, in this case, we must show whether individual intentions were to commit such an act and if that act was ever attempted. When one murders an individual or attempt to murder an individual, charges should be brought against them. The statutory standard for an Attempted charge is defined as ‘a person is guilty of an attempt to commit a crime if there was intent, substantial step toward committing the act, and failure to commit the crime (Lippman, 2010, pg. 191). There are three key elements behind an individual attempt at crime; “an intent or purpose to commit a crime, an act or acts toward the commission of the crime, and a failure to commit the crime” (Lippman, pg. 191). In this particular case there should have been a charge of attempted murder as the three elements exist. In Jack’s attempt to shot Bert, it showed intent, an attempt, and, fortunately for Jack, a failure at committing the actual crime. As you can see, by the steps outlined of Jack actions, when he approached the car to kill Bert his intention were to murder an individual. Per definition murder is defined as “the crime of unlawfully killing a person especially with malice aforethought” (Merriam-Webster, 2012). The unlawful killing took place when he shot at the two individual in the car, killing Pratt, however only showing attempt with Bert. Due...

...REVISION QUESTIONS You are required to prepare brief answers to these questions. Question 1 Jack advertised his car for sale for RM30,000 in a local newspaper on 1.2.2011. Tom saw the advertisement and went to Jack’s house to give him a cheque for the sum of RM25,000 on 3.2.2011. Jack refused to accept the cheque and Tom stated that he would sue Jack for breach of contract. The next day, 4.2.2011, Kevin inspected the car and later wrote to Jack enclosing a cheque for RM30,000 and saying that he would assume the car was his if he did not hear anything from Jack within 3 days. On 5.2.2011, Eric came with RM28,000 in cash to tell Jack that he wanted to buy the car. Jack accepted the money from Eric and allowed Eric to drive away the car. Please advise Jack on his liability in the above situation.

...others is driving around in my car and all of a sudden coming face-to-face with having a flat tire. Ive been in this situation so much i could probably teach a course on how to fix it. So i've decided to give my step by step list of steps i take in order to getting your vehicle back mobile. Before i start there will always be different variations of how to fix this particular problem because of different situations/environments, makes/models of cars and types of tires used on the vehicle. But with that being said, let me begin. Step 1- As soon as you find out you have caught a flat tire (the sound of your rim against the pavement/difference in drive should alert you to this matter) you should immediately try and find a flat surface/level of terrain to stop so you could have a leveled surface to keep your vehicle from rolling away from you. Step 2- Put your car in "park" , and apply the "parking brake." (if you weren't able to find a flat surface try and find a large enough object in order to place in front or back of the tires to help prevent from rolling and to keep the car stable as you prepare to work. Step 3- You will need to assemble your tools. (which should be a jack, spare tire/donut, and given what time it may be you might want to have a flashlight ready.) Step 4- Place your jack underneath your car onto the hard portion (straying way from the plastic portion that some cars may have) and start to raise the jack until it is snug with the car and the ground. Step 5-...
