Answer:
A. from zero at the center to maximum at the circumference.
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).

Answer:
a) P = 86720 N
b) L = 131.2983 mm
Explanation:
σ = 271 MPa = 271*10⁶ Pa
E = 119 GPa = 119*10⁹ Pa
A = 320 mm² = (320 mm²)(1 m² / 10⁶ mm²) = 3.2*10⁻⁴ m²
a) P = ?
We can apply the equation
σ = P / A ⇒ P = σ*A = (271*10⁶ Pa)(3.2*10⁻⁴ m²) = 86720 N
b) L₀ = 131 mm = 0.131 m
We can get ΔL applying the following formula (Hooke's Law):
ΔL = (P*L₀) / (A*E) ⇒ ΔL = (86720 N*0.131 m) / (3.2*10⁻⁴ m²*119*10⁹ Pa)
⇒ ΔL = 2.9832*10⁻⁴ m = 0.2983 mm
Finally we obtain
L = L₀ + ΔL = 131 mm + 0.2983 mm = 131.2983 mm
