Question

A steel rod is projecting out of a rigid wall. The shearing strength of steel is 345 MN/m2.The dimensions AB = 5 cm , BC = BE = 2cm. The maximum load that can be put on the face ABCD is:(neglect bending of the rod) (g = 10 m/s2)

(A)3450 Kg

(B)1380 Kg

(C)13800Kg

(D)345 Kg

Answer 1

Correct option (C)13800Kg

Explanation:

F = shear strength x area on which shear stress acts

= 345 × 106 × 4 × 10–4

= 138000 N = 13800Kg
