Question
An object's moment of inertia is $2.0 \mathrm{kg} \mathrm{m}^{2} .$ Its angular velocity is increasing at the rate of $4.0 \mathrm{rad} / \mathrm{s}$ per second. What is the torque on the object?
Step 1
Torque (Ď„) is given by the product of the moment of inertia (I) and the angular acceleration (α). This can be written as: \[Ď„ = Iα\] Show more…

An object's moment of inertia is $2.0 \mathrm{kg} \cdot \mathrm{m}^{2} .$ Its angular velocity is increasing at the rate of $4.0 \mathrm{rad} / \mathrm{s}$ per second. What is the net torque on the object?
An object whose moment of inertia is $4.0 \mathrm{kg} \mathrm{m}^{2}$ experiences the torque shown in figure 12 26. What is the object's angular velocity at $t=3.0 \mathrm{s} ?$ Assume it starts from rest. (FIGURE CAN'T COPY)
A constant torque is applied to a rigid body whose moment of inertia is $4.0 \mathrm{kg}-\mathrm{m}^{2}$ around the axis of rotation. If the wheel starts from rest and attains an angular velocity of $20.0 \mathrm{rad} / \mathrm{s}$ in $10.0 \mathrm{s},$ what is the applied torque?
