Problem 8-7

The block brake consists of a pin-connected lever and friction block at B. The coefficient of static friction between the wheel and the lever is ms = 0.3, and a torque of 5 N # m is applied to the wheel. Determine if the brake can hold the wheel stationary when the force applied to the lever is (a) P = 30 N, (b) P = 70 N. 200 mm 50 mm 400 mm P 150 mm O B A 5 Nm Prob. 87

Problem 8-7

The block brake consists of a pin-connected lever and friction block at B. The coefficient of static friction between the wheel and the lever is , and a torque of 5 is applied to the wheel. Determine if the brake can hold the wheel stationary when the force applied to the lever is (a) P = 30 N, (b) P = 70 N. Step by Step Solution

Step 1 of 10

In order for the break to hold the wheel, friction force at B must be less than its maximum friction force  (A) First, we’ll isolate and draw the free-body diagram of the wheel . Step 2 of 10
