Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaf…

Chapter 50, Problem 4SA

When the brakes are applied on a moving car, the frictional parts (brake or) are forced against the rotating parts of the car (brake or). The friction causes the rotating parts to slow down and stop. Just as the energy of the rotating parts is called kinetic, the friction used to stop them is called kinetic.

Students have asked these similar questions

Which of the following statements about friction is FALSE? A Friction force is always less than the force required to prevent motion. The total frictional force is dependent on the area of contact between the two surfaces. The direction of frictional force on a surface is such as to oppose the tendency of one surface to slide relative to the other. The magnitude of the frictional force is equal to the force which tends to move the body till the limiting value is D reached.

When stopping a car on an icy or wet road... or a dry road, for that matter... is it better to push the brake pedal hard enough to lock the wheels and make them slide? Or to push gently so that the wheels continue to roll? What is the point behind "anti-lock disk brakes"? Which coefficient of friction u, or uk is relevant to which case? (hint: start by considering the forces on different points on the wheel in each case, and calculate the largest possible deceleration for both conditions)

when two surfaces are in contact with one another, the amount of friction between them depends on the surface area. a. true b. false
