The shear strength, tensile strength and compressive strength of a rivet joint are 100 N, 120 N and 150 N respectively. If strength of the unriveted plate is 200 N, the efficiency of rivet joint is
Detailed Solution for Test: Design of Joints Level - 1 - Question 11

Shear strength, PS = 100 N

Tensile strength, Pt = 120 N

Compressive strength, Pc = 190 N

Strength of unriveted plate, P = 200 N

Efficiency of riveted joint is defined as ratio of the strength of riveted joint to the strength of unriveted solid plate.
