Question

4. A 7 inch long, hollow circular shaft has an outer diameter of 1.5 inches and a wall thickness of 0.125 inch. The shaft is fixed at one end and is subjected to a 5500-in-lbf torque and a 1200 lbf vertical load at the free end as shown. Select a material from Table A-20 to ensure a minimum factor a safety of 1.5 for torsion and of 1.3 for bending. What are the actual design factors of safety? Ans:

Solved by Expert Umar Sohail Qureshi

Step 1

Calculate the inner diameter of the shaft: Inner diameter = Outer diameter - 2 * Wall thickness Inner diameter = 1.5 inches - 2 * 0.125 inches Inner diameter = 1.25 inches Show more…
