The shear modulus of steel is 8.1 × 1010 n/m2. a steel nail of radius 7.5 × 10–4 m projects 0.040 m horizontally outward from a wall. a man hangs a wet raincoat of weight 28.5 n from the end of the nail. assuming the wall holds its end of the nail, what is the vertical deflection of the other end of the nail?

Explanation:

given,

shear modulus of steel = 8.1 × 10¹⁰ N/m²

radius of steel nail =  7.5 × 10⁻⁴ m

Projection outward = 0.040 m

Weight of wet raincoat = 28.5 N

Vertical deflection of other end of the nail = ?

we know

A = π r²

A = π x (7.5 x 10⁻⁴)²

A = 1.767 x 10⁻⁶ m²

Thus, the vertical deflection of the other end of the nail is

asthenosphere and convection
