...Essay Question 2: Refer to the following diagram Using the following sub headings, describe the key biomechanical principles involved in a baseball pitcher throwing a curve ball from right to left. a) Segmental Interaction (7 marks) Body parts move in a sequence to generate the largest force or accelerate possible. To sequentially produce a maximal force effectively, the following principles need to be applied: 1. The stronger and larger muscles of the thighs and trunk are moved first followed by the smaller and faster muscles. This is seen in diagram 1. 2. Sequentially accelerate each body part so that optimum momentum passes from one body part to the next. In the transition from diagram 1 to 2, we see this sequential acceleration of muscle movement. 3. Each body part should be stable so that the next body part accelerates around a stable base to transfer momentum. In pitching it is essential to adopt a wide stance to increase stability. This is done by placing legs further apart from each other. 4. Use as many body parts as possible, so force can be applies over the maximal possible time. The pitcher can increase number of segments by getting side on, whilst also uncocking wrist prior to throw. 5. Follow through is important to prevent deceleration of last segment and safe dissipation of force. This can be seen in the transition from diagram 3 to 4. 6. Ensure all forces are directed towards the batter (the target) b) Spin (6 marks) 1. As...

...nose high and nose low. The student must use proper instrument cross-check and interpretation, and applies the appropriate pitch, bank, and power corrections in the correct sequence to return the aircraft to a stabilized level flight attitude. Procedure: (Nose High) * Increase Power * Apply forward elevator pressure to lower the nose and prevent a stall * Correct the bank by applying coordinated aileron and rudder pressure to level the miniature aircraft and center the ball of the turn coordinator * Level pitch attitude is indicated by the reversal and stabilization of the ASI and altimeter needles. * Straight coordinated flight is indicated by the level miniature aircraft and centered ball of the turn coordinator Note* The corrective control applications are made almost simultaneously, but in the following sequence listed above. (Nose Low) * If airspeed is increasing, reduce power to prevent excessive airspeed and loss of altitude. * Correct the bank attitude and coordinated aileron and rudder pressure to straight and level flight by referring to the turn coordinator. * Raise the aircrafts nose to level flight by applying smooth back elevator pressure * This whole procedure should be done smoothly and all controls should be moved simultaneously * The attitude indicator and turn coordinator should be checked to determine bank attitude and then corrective aileron and rudder pressure should be applied. * The ball should always remain...

...Development and Applications of Acoustic Charge Transport CID #478 Physics 222 Term Paper #1 Abstract Acoustic charge transport is accomplished through the use of a surface acoustic wave passing through a low dimensional electron layer. The power efficiency is increased with a piezoelectric substrate. Quantum wires are formed with higher wave intensity, and quantum dots are formed with the interference of two waves. Such methods have applications in electronics. Excitons are preserved for longer times with the use of an acoustic charge transport system, which allows for the development and implementation of optoelectronic delays and storage devices. A common goal of much of today’s technological development is finding ways to make existing technology smaller or more efficient. This is especially apparent in electronics, where a constant push is made to make devices smaller, lighter, and more powerful. Acoustic charge transport (ACT) is a relatively new concept and technique which has applications in both electronics and optoelectronics, which uses light instead of electricity. Not only does ACT have applications in these areas, it has distinct advantages by being smaller and more efficient than currently employed systems. Acoustic charge transport, as the name suggests, is the moving of charge through the use of acoustic waves. The charge that is transported consists of electrons forming a lowdimensional layer, residing in a semiconductor film called...

...CHAPTER 1 INTRODUCTION 1.1 History A forklift (also called a lift truck, a high/low, a stacker-truck, trailer loader, side loader or a fork hoist) is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1920s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing. The forklift has since become an indispensable piece of equipment in manufacturing and warehousing operations. The middle 19th century through the early 20th century saw the developments that led to today's modern forklifts. The Pennsylvania Railroad in 1906 introduced battery powered platform trucks for moving luggage at their Altoona, Pennsylvania train station. World War I saw the development of different types of material handling equipment in the United Kingdom by Ransomes, Sims and Jeffries of Ipswich. This was in part due to the labor shortages caused by the war. In 1917 Clark in the United States began developing and using powered tractor and powered lift tractors in their factories. In 1919 the Towmotor Company and Yale & Towne Manufacturing in 1920 entered the lift truck market in the United States. Continuing development and expanded use of the forklift continued through the 1920s and 1930s. World War II, like World War I before, spurred the use of forklift trucks in the war effort. Following the war, more efficient methods for storing products in warehouses were being...

...BIOMECHANICS The term biomechanics means the study of the structure and function of biological systems using the methods of mechanics. Biomechanics studies the process of kinematics and used in the study of sports actions, such as the motion of throwing a baseball. Why do some golfers slice the ball? How can workers avoid developing low back pain? What cues can a physical education teacher provide to help students learn the underhand volleyball serve? Why do some elderly individuals tend to fall? We have all admired the fluid, graceful movements of highly skilled performers in various sports. We have also observed the awkward first steps of a young child, the slow progress of an injured person with a walking cast, and the hesitant, uneven gait of an elderly person using a cane. Virtually every activity class includes a student who seems to acquire new skills with utmost ease and a student who trips when executing a jump or misses the ball when attempting to catch, strike, or serve. What enables some individuals to execute complex movements so easily, while others appear to have difficulty with relatively simple movement skills? Although the answers to these questions may be rooted in physiological, psychological, or sociological issues, the problems identified are all biomechanical in nature. This book will provide a foundation for identifying, analyzing, and solving problems related to the biomechanics of human movement. Definition of Biomechanics The term biomechanics combines...

...processes were estimated to be more than $80 million. If the price paid for Torrington were too high, Ingersoll-Rand, rather than Timken, would capture the value of the synergies. In addition, given the large size of the acquisition, Timken was concerned about the impact on its balance sheet. If Ingersoll-Rand demanded a cash deal and if Timken raised the money with new debt, the increased leverage would almost certainly prompt credit agencies to downgrade Timken’s investment-grade rating. The Bearing Industry Bearings of various sizes and specifications found their way into everything from space shuttles to household appliances, automobiles, dentist drills, roller skates, and computer disk drives. In 2001, U.S. establishments involved in ball- and roller-bearing manufacturing employed more than 33,000 workers. The bearing industry was facing a variety of complex problems. Policies favoring the steel industry did not always consider the best interests of the bearing industry, which, as manufacturers of secondary steel products, was in the middle of the production chain. Because bearings were essential components of military and civilian machinery and equipment, the federal government had historically been a major customer. Nonetheless, foreign competitors had taken...
