Deflection of an Eccentric Tie

After collecting data and analyzing the results the group concluded that tension will always be greater than mass for uniform constant motion due to the presence of θ. As the length of the string for the flying toy increased, θ decreased in both trials for the cow and bat. For instance, when the bat had a length of 0.86m, the calculated θ was 34.4°, but when the length was shortened to 0.61m, the θ increased to 36.5°. The period was also shortened when the length decreased; therefore, velocity decreased as string length increased while acceleration increased with a

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

By using Eq (4.4) we can calculate for a [a= m/M+m * g, a = (20 g /(283.2 g + 20 g)) * 9.81 m/s2= 0.646 m/s2]. The value of a (a= 0.5067 m/s2 +/- 0.01709 m/s2) we calculated for is not consistent with the expected value of 0.646 m/s2. As stated before, the probably cause of the inconsistency is the slight discrepancy during the experiment.

In order to calculate frequency, the free body diagram must be taken into consideration in order to calculate the force of tension. In this lab, the force of tension and gravity are assumed to be the only forces. Furthermore, the

The active, passive, and total forces were then plotted against the length of

Our experiment was to test whether or not, the amount of air in a soccer ball would affect its travel distance. Along with that, we aimed to find out which amount of air would deliver the furthest distance when the ball was kicked. Which, we believed would be useful and beneficial information for those who play soccer. Especially those who play the sport professionally, for we used the ball size of which FIFA requires for their games. And with this information, they can know how much air to fill their balls with, to gain a greater distance, for the best performance. In order to conduct the experiment, we decided to create and build our own pendulum. Which we did to ensure that the amount of pressure applied to the ball when kicked would be

Experiment Two: Stiffness Report from laboratory work performed on 12 May 2011 as a part of the unit of study CIVL2201 Structural Mechanics

The percent error between the potential energy and kinetic energy varies from 0.77% to 7.56 percent. A comparison between the kinetic energy and potential energy is graphed in Figure 1. The two forces compare well showing that the potential energy lost is equal to the kinetic energy gained. Using the best fit, the kinetic energy versus the potential energy is presented in Figure 2. The slope of the line is 0.9511, which represents that the potential energy lost is equal to the kinetic energy gained. Since the ratio of kinetic energy to potential energy is one, it implies that all the potential energy to start with is transformed to kinetic energy. The R2 is 0.9913. The difference between the results of the potential energy and the kinetic energy shows that the experiment was a success for all ranges. Overall, the experiment demonstrates the principle of conservation of

Computation was done by placing the meter stick on the stand suspending m1=100g at 30-cim, m2=200g at 70-cm position. M3=50g was the calculated mass for the system to be at equilibrium. M1=100g and was at the 20-cm position and m2=200g while on the 60-cm position. Both the results and percent error of the experimental value were calculated.

The purpose of this experiment is determine the resultant of several concurrent coplanar forces though the use of graphical addition, rectangular components by graphical and trigonometric methods, and the use of the a force table. The magnitude through trigonometric methods was 1212.4 newtons,and the the magnitude through graphical addition was 1184 newtons. Due to time constraints, we were not able to use the force table.

We are using nitinol (nickel titanium alloy) beam it’s having a low modulus of elasticity (E) which shows good spring back behavior which regain its original shape after removing external load. Who’s bending stiffness is low compared to other material like stainless steel. Due to this property at very low external load large deflection take place in the beam. We are going to find the deflection in

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.

Following tables and graphs show the result of the experiment. The tables will demonstrate the experimental and theoretical deflection for each case. The graphs will show the relationship between the load applied and deflection, in addition to compare the experimental deflection and theoretical deflection.
