Question

Question 1

The value of shear stress which is induced in the shaft due to the applied couple varies

Oa from zero at the center to maximum t the circumference
Ob from maximum at the center to minimum at the circumference
Oc from minimum at the center to maximum at the circumference
Od from minimum at the center to maximum at the circumference​

Answer 1

The correct answer is A

Answer 2

A. from zero at the center to maximum at the circumference.

Step-by-step explanation:

The shear stress describes the process where a body deforms as a result of a part sliding over the other.

The value of shear stress which is induced in the shaft due to the applied couple varies from zero at the center to maximum at the circumference.

The shear stress in a shaft is given by this formula;

τ = Tr/I

where;

τ = shear stress (MPa).

T = applied torque (Nmm).

r = distance from center to stressed surface in the given position (mm).

I = polar moment of Inertia of cross-sectional area (mm).
