Chapter 7, Problem 4P
A geared industrial roll shown in the figure is driven at 300 rev/min by a force F acting on a 3-in-diameter pitch circle as shown. The roll exerts a normal force of 30 lbf/in of roll length on the material being pulled through. The material passes under the roll. The coefficient of friction is 0.40. Develop the moment and shear diagrams for the shaft modeling the roll force as (a) a concentrated force at the center of the roll, and (b) a uniformly distributed force along the roll. These diagrams will appear on two orthogonal planes.
Problem 7–4
Material moves under the roll. Dimensions in inches.

according to Maximum Shear Stress theory ,Calculate the factor of safety of the shaft When it is subjected to an end thrust producing stress of 90 MPa and the maximum shearing stress on the surface arising from torsion is 60 MPa.The yield point of the material in simple tension was found to be 300 MPa.
When drilling a well at a constant angular velocity, the bottom end of the drill pipe encounters a torsional resistance TA. Also, soil along the sides of the pipe creates a distributed frictional torque along its length, varying uniformly from zero at the surface B to tA at A. Determine the minimum torque TB that must be supplied by the drive unit to overcome the resisting torques, and calculate the maximum shear stress in the pipe. The pipe has an outer radius ro and an inner radius ri.
