Consider the following statements:
1.On planes having maximum and minimum principal stresses, there will be no tangential stress.
2.Shear stresses on mutually perpendi-cular planes are numerically equal.
3.Maximum shear stress is equal to half the sum of the maximum and minimum principal stresses.
Which of these statements is/are correct?
1. On principal planes, shear stress is zero - Correct.
2. Shear stresses on mutually perpendicular planes are equal in magnitude - Correct.
3. Maximum shear stress is:
It is half the difference, not half the sum – Incorrect
