Final answer:

Braking from a brake chamber containing a power spring is described as abrupt and jolting since the power spring is a fail-safe mechanism that acts quickly and with significant force in the event of air pressure loss in the brake system.

The correct option is b) Abrupt and jolting

Step-by-step explanation:

When examining the effects of braking from a brake chamber containing a power spring, it's important to understand that the purpose of the power spring is to provide a fail-safe mechanism. This means that if there is a loss of air pressure in the brake system, the power spring will apply the brakes to ensure the vehicle can stop.

The correct description of the braking from such a system would be b) Abrupt and jolting. Because the power spring is designed to engage fully in the event of system failure, it will cause the brakes to apply quickly and with significant force, leading to an abrupt halt rather than a gradual slowdown.

Braking from a brake chamber containing a power spring can be described as gradual and controlled. When the brake pedal is pressed, air pressure is released into the brake chamber, causing the power spring to compress. As the power spring compresses, it exerts force on the brake shoes, leading to a gradual and controlled braking action.

The correct option is b) Abrupt and jolting
