Transcribed Image Text:50 mm and the coefficient of friction between the blocks and the drum is 0.25.
30°
Q9/ braking system has its braking lever inclined at an angle
of 30° to the horizontal plane, as shown in Figure. The
diameter of the brake drum is 540 mm and rotates
clockwise; the angle of contact surface of the block is
50. At the instant the lever is pressed on the brake drum
with a vertical force of 600 N. The coefficient of friction
between the brake shoe and the brake drum is 0.4.
Assume that the lever and brake shoe are perfectly rigid Brake drum-
and possess negligible weight. Find the braking torque.
