Question

At a point in a strained material, the intensities of normal stresses on two planes at right angles to each other are 35 N/mm2 and 20 N/ mm2 both tensile. They are accompanied by shear stress of 15 N/ mm2. Find the principal planes and principal stresses. Find also maximum shear stress.

Answer 1

Answer:

Solution:

Given data: px = 40 N/mm2, py= 20 N/mm2 and q = 20 N/mm2.

At a point in a body, there are two mutually perpendicular stresses of 80 N/mm2 and 40 N/mm2, of tensile nature. Each stress is accompanied by a shear stress of 60 ...
