FIGURE shows a centrifugal clutch. Each of the three equally spaced shoes with linings has a mass of 5 kg and is restrained radially by a tension spring as shown.
For the stationary position shown, the residual tension in each spring is 200 N. Neglecting the mass of the springs, determine:
(a) the speed of rotation at which the shoes commence to move radially outwards
(b) the speed of rotation at which the shoes first make contact with the inner surface of the clutch drum
(c) the power transmitted by the clutch when the speed of rotation is 600 rev min-I. Take the coefficient of friction between the shoe linings and drum surface as 0.3.
A 119-µF capacitor is connected to an ac generator with an rms voltage of 20.0 V and a frequency of 121.0 Hz. What is the rms current in this circuit
When cars are equipped with flexible bumpers, they will bounce off each other during low-speed collisions, thus causing less damage. In one such accident, a 1850car traveling to the right at 1.40 collides with a 1400 car going to the left at 1.10 ..
