SOLVED PROBLEM 2.10

At a certain point in a strained material the direct stresses on the two planes at right angles to each other are 40 N/mm² (along the horizontal direction) and 20 N/mm² (along the vertical direction). They are accompanied by a shear stress of 20 N/mm². Compute the principal stresses and any one of the principal planes (Anna Univ., June 2005, CE).

Solution:

Given data: p_x = 40 N/mm², p_y= 20 N/mm² and q = 20 N/mm².

 

SOLVED PROBLEM 2.11

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 ...
