Question

The block brake is used to stop the wheel from rotating when the wheel is subjected to a couple moment by:

a) Increasing the friction between the brake and the wheel
b) Employing a magnetic field to halt wheel movement
c) Initiating a counter-torque to offset the couple moment
d) Reducing the wheel's angular momentum

Answer 1

The block brake is used to stop the wheel from rotating by increasing the friction between the brake and the wheel.

Step-by-step explanation:

The correct answer is a) Increasing the friction between the brake and the wheel. The block brake is specifically designed to increase the friction between the brake and the wheel, which in turn stops the wheel from rotating. By increasing the friction, more force is applied between the brake and the wheel, resisting the couple moment and preventing the wheel from rotating.
