Question

Question 1 Design a cotter joint as shown in the figure to support a load varying 45 kN in tension and 45 kN in compression. The allowable shear stress is 50 MPa and crushing stress 90 MPa. The allowable tensile and compressive stress is 80 MPa. Let the thickness of the cotter be the diameter of the spigot divided by four and the length be three times the rod diameter. Let the length e be 1.2 times the rod diameter.

Step 1

Determine the diameter of the spigot (d3): Since the thickness of the cotter is the diameter of the spigot divided by four, we can assume the thickness (t) to be d3/4. Show more…
