Strength of MaterialsTheory of Structures and DesignHARD
Choose the correct answer
A
1.5 times average shear stress
B
zero at neutral axis
C
equal to average shear stress
D
2 times average shear stress
Correct Answer
A. 1.5 times average shear stress
Why is this the answer?
For a rectangle, shear stress distribution is parabolic and maximum at the neutral axis is 1.5 times average shear stress.
