Question

A steel rod is projecting out of a rigid wall. The shearing strength of steel is

345MNm^{- 2}

. The dimensions

AB = 5cm, BC = BE = 2cm

. The maximum load that can be put on the face

ABCD

~is : (neglect bending of the rod) (

g = 10ms^{- 2}

)

Correct answer: C. 13800 kg

F = shear strength x area on which shear stress acts = 3 4 5 × 1 0 ^ 6 × 4 × 1 0 ^ - 4 = 1 3 8 0 0 0 N So the mass that can be placed~ = 13800kg
