Final answer:
The statement is True; safety requires that vehicles or equipment on inclines have brakes and chocks applied. This is to counteract gravity and prevent movement, leveraging the principles of static and kinetic friction.
Step-by-step explanation:
The statement that vehicles or equipment parked on an incline will have the parking brake set, and the wheels will be chocked is True. This is a safety measure to prevent the vehicle or equipment from rolling down the incline due to gravity. The parking brake provides resistance to motion, while wheel chocks act as physical blocks that prevent the wheels from moving. This principle is related to the concepts of static and kinetic friction, where static friction helps to keep a stationary object at rest, and once an object is in motion, kinetic friction acts upon it which is typically less than static friction.
When discussing inclined planes and the forces acting on objects placed on them, it's important to understand how static and kinetic friction work together. Static friction is what keeps an object at rest from moving until a certain amount of force is applied, while kinetic friction is the force that acts against the motion once the object starts moving. For example, when driving and coming to a stop, easing up on the brake pedal allows for a smoother stop because it reduces the motion that would be caused by the sudden transition from kinetic to static friction.
