Definitions and Equations: Moment of Inertia (D): Tendency to resist angular acceleration; the angular equivalent of...
1. The moment of inertia (sometimes referred to as a “swing weight”) is a measure of the resistance to rotation about a particular axis. It is often expressed as Ia = mka2 where m is the mass of the object and ka is the radius of gyration about the axis of rotation. The radius of gyration ka for the arm about its COM = 0.368*(arm length). Compute the moment of inertia of the arm in the extended position about its...
4. Suppose we want to calculate the moment of inertia of a 67 kg skater, relative to a vertical axis through their center of mass. a. First calculate the moment of inertia (in kg.m2) when the skater has their arms pulled inward by assuming they are cylinder of radius 0.125 m. b. Now calculate the moment of inertia of the skater (in kg.m2) with their arms extended by assuming that each arm is 5% of the mass of their body....
Suppose we want to calculate the moment of inertia of a 67 kg skater, relative to a vertical axis through their center of mass. Part (a) First calculate the moment of inertia (in kg⋅m2) when the skater has their arms pulled inward by assuming they are cylinder of radius 0.11 m. Part (b) Now calculate the moment of inertia of the skater (in kg⋅m2) with their arms extended by assuming that each arm is 5% of the mass of their...

the list of equations to list are attached! thanks! 6. A playground merry-go-round, i.e., a horizontal disc of radius 3 m that can rotate about a vertical axis through its center, is rotating at an angular speed 1/s (measured, as usual, in terms of radians). The moment of inertia of the merry-go-round with respect to that axis is 3000 kg m? A student of mass 80 kg is standing at the center of the merry-go-round. The student now walks outward...
17. [1pt) A wheel of mass m = 1.87 kg and moment of inertia, I = 1.530 kg.m- is supported by a pivot a distance d=0.17 m from the wheel, as shown in the diagram. The axle through the wheel is initially in the horizontal plane, as shown, and the wheel is spinning about the axis in the sense indicated, with an angular velocity o = 90 rad's. Answer the following three questions using the choices given; c.g., if the...
Part A - Angular Acceleration of the Rod Learning Goal: To apply the equations of motion to a system that involves rotation about a fixed axis and to use this information to determine key characteristics. The slender rod AB shown has a mass of m = 71.0 kg and is being supported by a rope and pulley system stationed at C. Starting from rest in the position shown), the rope and pulley system tug on the rod causing it to...
