Question

A steel plate of width 120 mm and of thickness 20 mm is bent into a circular arc of radius 10 m. Determine the maximum stress induced and the bending moment which will produce the maximum stress. Take e = 2 x 105 n/mm2.

Answer 1

The magnitude of the pure moment m will be 2 x 10^5.

Explanation:

• Width of steel fleet = 120 mm (Given)
• Thickness of steel fleet = 10 mm
• Circle of radius = 10 m

M/I = E/R

Therefore, M = EI/R

R = 10000 mm

I = 1/12 × 120 × 10³mm^4 = 10^4 mm^4

E = 2 x 10^5 n/mm²

M = 2 x 10^5× 10^4/ 10000

= 2 x 10^5

Thus, the magnitude of the pure moment m will be 2 x 10^5.
