Do the values agree? Describe what specific effects might produce a systematic error in your result. Compare your calculated disk mass to that using the large scale at the front of the room. Propagate the uncertainty in your measurements to your result.Explain your calculation of the disk mass step-by-step, and give the results leading to your answer.To know how the polar moment of inertia is different from the moment of inertia, read our. The table below summarizes the equations for computing I of objects of some common geometrical shapes. From the applied torque, disk radius, and angular acceleration, calculate the disk mass. Therefore by finding the moment of inertia about the x and y-axis and adding them together we can find the polar moment of inertia. For objects with simple geometrical shapes, it is possible to calculate their moments of inertia with the assistance of calculus.From the radius of the axle pulley, calculate the torque acting upon the spinning disk.From the initial height and time it takes to reach the ground, determine the acceleration, and thus the tension force in the string. Wrap the string of the hanging mass around the axle pulley of the disk on the Rotational Motion Apparatus and drape the string over the pulley clamped to the table edge.
