Two cars, one with and one without ABS, are stopping from a speed, v0 = 100 km/h, by full braking. The first car without ABS has a kinetic friction, μ = 0.45, and the second car with ABS has a coefficient of friction, μ = 0.70 (ideal ‘limiting static friction’). What is the braking time, tB, in seconds of the car without ABS?

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 shaft to the driven shaft.
