Marks: +1, -0

A wire of circular cross-section of diameter 1.0 mm is bent into a circular arc of radius 1.0 m by application of pure bending moments at its ends. The Young’s modulus of the material of the wire is 100 GPa. The maximum tensile stress developed in the wire is ____________ MPa.

Your Answer:

Validate

Solution:

Tensile stress

σ=\;{E}/{R} y=\;{100 × 10^{3}}/{1}(\;{1}/{1000 × 2})=50 {MPa}
