Consider a solid rod of mass $m$ and uniform density resting against a vertical wall and horizontal floor as shown in the figure. The coefficients of friction of the rod with the wall and with the floor are given to be $\mu_1$ and $\mu_2$ respectively. Gravity is acting downwards with acceleration due to gravity $g$. What should be the value of the inclination angle $\alpha$ so that the rod stays in equilibrium? IAT (IISER) 2020 Physics - Rotational Motion Question 4 English

An inextensible cord of negligible mass passes over the rim of a solid disc of mass $M$ and radius $R$. The disc is free to rotate about an axis passing through the centre perpendicular to the plane of the screen, as shown in the figure. Two blocks of masses $M$ and $\widetilde{M} / 2$ are attached to the two free ends of the cord. Assume that there is no slipping of the cord on the disc. The acceleration due to gravity is $g$. What is the value of the angular acceleration of the disc? IAT (IISER) 2024 Physics - Rotational Motion Question 3 English

A circular disk of mass $M$ and radius $R$ is rotating clockwise with a uniform angular velocity $\omega$ about an axis passing through the centre, normal to the disk. At time $t=0$, a torque $T$ is applied along the same axis to oppose the rotation of the disk. What is the angular displacement $\theta$ (measured from $t=0$ in the clockwise direction) that the disk attains before it starts rotating counterclockwise?

A

\(\theta=\frac{\omega^2 M R^2}{4 T}\)

B

\(\theta=\frac{\omega^2 M R^2}{8 T}\)

C

\(\theta=-\frac{\omega^2 M R^2}{4 T}\)

D

\(\theta=-\frac{\omega^2 M R^2}{8 T}\)
