Which requires the most torque to achieve the same angular acceleration about its center? Assume all objects have the same mass and radius.
Group of answer choices
A. A solid disk (I = 1/2MR^2)
B. A ring (I = MR^2)
C. A hollow sphere (I = 2/3MR^2)
Homework Answers
We know that the torque is
.
...1
As you are know I ring >I hollow sphere >Isolid disc ..2
From equation 1 and 2
The ring requires most torque to achieve the same angular acceleration about its center so answer is (B).

A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...
