a) A square plate has mass 0.600 kg and sides of length 0.150 m. It is free to rotate without friction around an axis through its center and perpendicular to the plane of the plate. How much work must you do on the plate to change its angular speed from 0 to 40.0 rad/s? Express your answer with the appropriate units. b) How much work must you do on the plate to change its angular speed from 40.0 rad/s to...
Question 14 In Figure (a), a metal plate is mounted on an axle through its center of mass. A spring with k = 2600 N/m connects a wall with a point on the rim a distance r = 4.00 cm from the center of mass. Initially the spring is at its rest length. If the plate is rotated by 7º and released, it rotates about the axle in SHM, with its angular position given by Figure (b).The horizontal axis scale...

The 24 cm diameter disk in the figure can rotate on an axle through its center. What is the net torque about the axle if F = 26·N?
The bar shown in figure below can rotate around the axis indicated by the dot counter clockwise. If a net torque of 3.5 N.m is experienced by the bar about the axis. (a) Draw a free body diagram, showing all horizontal and vertical forces acting on the bar. (b) Calculate the acting force F on the bar in N. (c) Calculate the angular acceleration in rad/s2 if the moment of inertia of the bar's is 0.5 kg.m?
A square metal plate 0.180 m on each side is pivoted about an axis through point O at its center and perpendicular to the plate. Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F1 = 22.0 N, F2 = 26.0 N, and F3 = 11.0N.
3) A horizontal circular platform can rotate around a vertical axis at its center with negligible friction. You decide to use the rotating platform to design a procedure that will allow you to determine the unknown rotational inertias of different objects, for example a bowl. You know the rotational inertia of the platform Ip. Which of the following procedures would serve your task? Comment on why. (More than one answer could be correct). Comment on the procedures that are not...

The moment of inertia of the human body about an axis through its center of mass is important in the application of biomechanics to sports such as diving and gymnastics. We can measure the body's moment of inertia in a particular position while a person remains in that position on a horizontal turntable, with the bodys center of mass on the turntable's rotational axis. The turntable with the person on it is then accelerated from rest by a torque that...
