d. All of the above options are the best way to test if your vehicle's spring brakes come on automatically.
Spring brakes aren't air implemented like carrier brakes. They apply while air pressure leaves the brake chamber and release when air pressure builds up in the chamber. Spring brakes use a distinctive form of brake chamber from carrier brakes.
The spring brakes will come on while the air strain drops into the range of 20 to forty-five psi. A closely loaded automobile will take a protracted distance to forestall because the spring brakes do not work on all axles.
Usually, spring brakes are used as a parking brakes. They can be observed at the rear axle of heavy vans. The spring brakes work like this: The stress is carried out to the spring facet, which lets in the parking brake disengage. while the spring is decompressed (at 20 lbs), parking brakes had been applied.

Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.
