The block brake consists of a pin-connected lever and friction block at BB. The coefficient of static friction between the wheel and the lever is μsμs = 0.3, and a torque of 5 NN ⋅⋅ mm is applied to the wheel. Determine if the brake can hold the wheel stationary when the force applied to the lever is (a) PP = 30 NN, (b) PP = 70 NN.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
