Allowable Stress Design - Factor of Safety - Strengths of Materials

Instagram:   / engineering_made_possible   This video shows how the Factor of Safety/Design Factor is used to determine the maximum allowable stress in designing structures such that failure does not occur. (0:00) Allowable Stress Design: Factor of Safety/Design Factor (3:00) Factor of Safety Equation (3:51) Problem statement: The joint is fastened together using two bolts. Determine the required diameter of the bolts if the failure shear stress for the bolts is 350 MPa. Use a factor of safety for shear of F.S. = 2.5.
