engineering recuitment GATE CE 2023-24 Test Series Strength of Materials Principal Stress or Strain Principle Stress
At a point in a material subjected to two dimensional stresses, the stress on a certain plane are σ1 and τ1 shear and on another plane the stresses are σ2 and τ2 shear as shown in figure.
Which of the following is correct? Assume σ1 is greater than σ2
1
The angle between XY and XZ plane is half of the angle between both co-ordinates of plane at centre of mohr's circle.
2
Radius of mohr's circle is equal to half of difference of principle stresses.
3
Maximum principle stress is the sum of σ1 and maximum shear stress.
4
If τ1 is equal to τ2 then angle between XY and XZ plane will always be at right angle.
