Vernier Caliper Lab Report

Pages 6
A Vernier caliper was used to measure the thickness of the three ropes. There is no zero error in the equipment I used, so there is no systematic error in the measurements. It would be essential to check the apparatus before conducting the experiment, since the variables have an expositional relationship, it is possible that the uncertainties in the values would lead to an entirely different equation. In my experiment, although the systematic errors for the measurement of rope width is eliminated, there still exists some random errors in the values. This might be due to the property of the rope used. Aiming for a better quality, the rope producers would make the rope soft and elastic, so that the rope would not break easily while hanging large weighted objects. However, this caused the rope to be easily compressed by the Vernier caliper. …show more content…
Therefore, this caused some random errors in the measurements for the rope’s diameter. However, luckily the result equation of the investigation had shown that there is no direct relationship between the thickness of the rope and the maximum tension force it can hold, so …show more content…
Besides, ropes with large friction coefficients such as straw ropes would have rough surfaces, if these types of ropes were used to carry out the experiment, the experimenter should wear gloves to avoid

...LENGTH: VERNIER CALIPER AND MICROMETER CALIPER A. L. P. Libera, N. C. Lindog, A. D. T. Manlagnit, M. L. C. G. Marasigan, J. F. R. Marquez, J. M. M. Mendones College of Engineering, Adamson University Abstract THIS LABORATORY REPORT PRESENTS THE ACCURACY OF MEASUREMENTS USING THE CALIPER. THE MAIN OBJECTIVE OF THIS LABORATORY ACTIVITY WAS TO BE ABLE FOR THE STUDENTS TO FAMILIARIZE ON HOW TO USE THE CALIPERS AS INSTRUMENTS FOR MEASURING PURPOSES. ANOTHER PURPOSE OF THIS EXPERIMENT IS TO RETAIN OR MINIMIZE THE PERCENTAGE ERROR AND PERCENTAGE DIFFERENCE OF THE PREVIOUS ACTIVITY TO SHOW THAT INSTRUMENTS USED FOR MEASURING ARE MORE ACCURATE. 1. INTRODUCTION The goal of physics is to provide an understanding of nature. The science of physics was developed to explain our physical environment.  In no subject does measurement play as important a role as in science. Real science cannot exist without measurement. Calculating accuracy reveals how close a set of measurements are to an accepted reference or true value. This differs from precision, which describes how close the measurements are to each other. Determining the accuracy of a measurement usually requires calibration of the analytical method with a known standard. Accuracy in measuring is knowing the  smallest reading that can be accurately measured while using an instrument or a device. The two common instruments used in measuring that increase the accuracy are the vernier caliper...

Tension Report

...Shear Box Report Abstract This repot describes the Shear Box test based on two types of soil that are loose soil and dense soil. The test has shown that the use of dry river sand under different densities to underestimate the shear strength parameters, the soil cohesion and the angle of friction with regard to the relationship between soil density and shear strength. Introduction The aim of the Shear box test was to determine the shear strength of sand using the shear box teat, and to investigate the effect of soil density on the strength. The shear strength of a soil is its resistance to shearing stresses. It is a measure of the soil resistance to deformation by continuous displacement of its individual soil particles. To investigate more about the behavior of the soil, a Mohr-coulomb theory has been introduced. This theory states that a material fails because of a critical combination of normal stress and shear stress, and not from their either maximum normal or shear stress alone. the limiting shear stress( the shear strength, t) that may be applied to any plane in the soil mass is found to be given by an equation of the form: τ = c + σ tan(φ) where σ = normal stress on the failure plane φ = angle of friction c = (apparent) cohesion The parameters C and φ are not generally soil constants. They also depended on the use of total or effective stresses. In terms of effective stress the failure criterion is written: τ = σ' tan(φ') + c' ...

In order to get a brief idea of the possible results, a literature review of some of the previous papers on similar topics was done. We designed our experiment based on CCRD, but due to time constraints and the shortage of raw material we had to use the full factorial method to vary parameters of our experiments. Introduction Polyvinyl chloride, commonly abbreviated PVC, is the third-most widely produced plastic after polyethylene and polypropylene. PVC is used in construction because...
