Torsion Measurement Lab Report Introduction The application of a given torque on the shaft whether stationary or in rotational motion generate shear stress as the shaft twists. The presence of bending or stretching force components makes the sample material to fail. Nov 20, 2014 · Conclusion In summary, this lab displays that the change in momentum of an object in motion is equal to the impulse on that object. As the car rolled down the track in the positive direction, it had a positive momentum, and the tension then increased in the elastic cord, pulling the car in the negative direction and changing its momentum from ... 1.2 Use of Rotary Motion Sensor or its (related work) • Measure the Rotational Inertia of Ring and DIsc. • Measure the Torque applying on three step pulley. • Measure the change of Angular velocities and Angular Acceleration. • Study damped and undamped harmonic motion using a mass and string system. 1.3 Specifications When it comes to Rotational Moment of Inertia, the orientation of how the object rotates becomes a factor because there are some orientation like in the experiment where the center is on the diameter, the weight is not, distributed which result to a weaker Moment of Inertia. Conclusion This experiment analyzed rotational motion in terms of torque, angular measurements, and moment of inertia. As said in the introduction, we know that linear speed is dependent on it’s distance away from the center of rotation.

In this experiment both the moment of inertia Iand the torsional constant of the Maxwell pendulum will be determined. In rotational motion, the moment of inertia I(which is analogous to mass min linear motion) depends on way in which the mass is distributed. rotational motion what the mass of an object is to translational motion. This analogy is illustrated schematically in Figure 1 below. Figure 1. Rotational vs. translational motion In this investigation, you will study how an object’s moment of inertia affects an object's rotation. You will also study the motion of several simple objects The motion of a unyielding device is due to the consolidation of the rotation and translation to different distances of which the object makes. The rotational inertia, I, of a object that is rotating has a fixed axis that measures the resistance of the object to the angular According to the Newton’s first law of motion, when the object is moving, it wants to keep going continually likes that, unless there is the force acting on the object. This law also applies to the rotational motion too, but we call it the centrifugal force that is not the real force because it is just an illusion force of our brains. Lab II) and constant velocity motion in a horizontal direction. Projectile motion lab report - Quality service and affordable drugs. Complete discussion of vector algebra see Halliday and and Resnick's. Your lab report should include the answers to all of the questions. The hypothesis and conclusion sections of your lab report will be. What is expected from your lab reports will be. Atwood s name: ballistic pendulum quintin t f ma c, at 11, the conclusion lab report. For experiments on the range of the projectile, the pendulum can be swung out of the way. Each lab report is graded on a 20 point basis and shall consist of. Figure 4.1: Ballistic Pendulum (Spring Gun). Rotational motion is more complicated than linear motion, and only the motion of rigid bodies will be considered here. A rigid body is an object with a mass that holds a rigid shape, such as a phonograph turntable, in contrast to the sun, which is a ball of gas. Nov 24, 2012 · Conclusion: In this lab, we learned how to in vestigate the conditions for rotational equilibrium of a rigid bar, and how to determine the center of gravity of a system of masses. We learned that t orque is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. The magnitude of torque depends on three quantities: the ... the Motional Tutorial at the end of lab, you may want to write this conclusion before you leave lab. Tutorials turned after the end of lab will receive at most 50% credit. Before you leave the lab please: Lower the end of the track toward the end of the table so that it rests on the table. Quit Capstone and straighten up your lab station. Product Summary In this experiment, the rotational inertias of a ring and a disk are determined by applying a torque to the object and measuring the resulting angular acceleration. A known torque is applied to the pulley on the Rotary Motion Sensor, causing a disk and ring to rotate. Physics 2015- Lab 7 Rotational Motion Lab 7 - Rotational Motion Purpose: This Lab is intended as an introduction to the concepts of rotational inertia, rotational energy, and angular momentum. We will calculate these values through three “standard” setups that you may be familiar with from your lecture series. The equation of motion for a wheel attached to the free end of a twisting spring, as shown in Figure-1, is given by: I Kθ θ + = 0 (1) Where I s the moment of inertia for the wheel (kg.m 2) θ is the angular displacement K is the rotational flexibility factor GJ K L After some reading – which may resemble the pre-lab of this lab unit – you conclude that the culprit is something called “moment of inertia” and decide to experiment with how rotational motion depends on how the mass is distributed in the rotating bodies. You will observe the behavior of a system similar with the one in the scenario: a block will be allowed to fall pulling on a thread wound around a small pulley. Rotational inertia is a similar concept applied to objects whose motion is rotational instead of linear. The rotational inertia of an object is that object's resistance to a change in its angular velocity. That is, if an object is spinning, it has a tendency to keep spinning until a net torque acts upon it. Apr 12, 2015 · Conclusion. The purpose of this mission was to help Hercules understand the relationship between frequency and radius of the motion, the mass of the sac, and the magnitude of the force causing the motion. The hypothesis developed before the experiment was the relationships between the given variables. The primary content of Physics 131L is mechanics, vectors, statics, uniform motion, accelerated motion, work and energy, momentum, and rotational motion. TEXT(S) ü The Physics 131 Laboratory Manual is available at the Bronco Bookstore. Theoretically, the rotational inertia, I, of a point mass is given by I = MR2, where M is the mass, R is the distance the mass is from the axis of rotation. To find the rotational inertia experimentally, a known torque is applied to the object and Lab II) and constant velocity motion in a horizontal direction.
