QUESTION:
The bell crank fits loosely into a 0.5-in-diameter pin. Determine the required force P which is just sufficient to rotate the bell crank clockwise. The coefficient of static friction between the pin and the bell crank is \(\mu_{\mathrm{s}}\) = 0.3.
ANSWER:
Step 1 of 9
In this problem, we want to determine the required force that is sufficient to rotate the bell crank clockwise as shown in the figure below. The given data are as follows:
- in, the diameter of the pin
- , the coefficient of friction between the pin and the bell crank
- The crank will turn clockwise
