Braking System MCQs

A braking torque of 2 kN-m is applied on a machine member to reduce the speed from 2000 rpm to 500 rpm in 10 sec. The specific heat of the brake material is 500 J/kg °C. The temperature rise for the brake per unit mass during braking period is

The service brakes employed in cars are usually operated

The main component of air pressure brake is

The following factor(s) contribute to the effectiveness of the brakes

What is the braking torque at leading shoe if resultant frictional force acts at a distance of 250 mm from the brake drum center, coefficient of friction between the shoe and the drum as 0.5, the free ends of the two shoes are pushed apart with a force of 300 N which is acting at a distance of 320 mm from anchor, and two shoes are anchored together 170 mm away from the brake drum center?

In an automotive brake system, balance between front and rear braking is ensured with the help of:
