**Unformatted text preview: **of 120, let the friction surface of the brake shoe be and centrally located (centered about the horizontal line shown through each shoe). (a) Calculate shoe size, for the left shoe such that the maximum pressure on each shoe is the same (this will make them tend to wear at the same rate). (b) Calculate the braking torque on each shoe, and find the total braking torque. Problem 3. Use the geometry and loading of Problem 1, but apply the short shoe approximation to estimate the average pressure on both shoes, the torque capacity of each shoe, the total torque capacity, and the pin reaction forces on each shoe. Compare the short shoe results with the long shoe results from Problem 1 above....
