Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

**Problem Statement:**

A block \( m = 5 \, \text{kg} \) sits on a horizontal surface with a coefficient of friction \( \mu = 0.2 \) between the block and the surface. A string runs from this block over a cylindrical wheel with radius \( R = 10 \, \text{cm} \) and mass \( m_c = 2 \, \text{kg} \). It is attached to a hanging \( 7 \, \text{kg} \) mass.

a. Find the acceleration of the masses, the angular acceleration of the wheel, and the tension in the string on each side.

b. Use acceleration to find the velocity after block \( M \) moves down by \( h = 0.5 \, \text{m} \).

**Diagram Description:**

The diagram shows:
- A block of mass \( m \) on a horizontal surface.
- The string connects this block to a cylindrical wheel at one end.
- The wheel then connects to a hanging block of mass \( M \) using the same string.

**Solution Steps:**

To solve this problem, apply Newton’s laws of motion and rotational dynamics. Consider the forces acting on each block and calculate the system's acceleration, angular acceleration, and string tension.

For part (b), apply kinematic equations to determine the velocity after the block descends by 0.5 meters.
