engineering recuitment UKPSC Polytechnic Lecturer Mock Test 2024 Strength of Materials Shear Stress and Bending Stress
Which of these is incorrect regarding shear stress distribution in beam:
1
Average shear stress in rectangular section is 0.67 times the maximum shear stress.
2
Shear stress is assumed constant along width and variation is considered along depth.
3
The maximum shear stress in triangular section will occur at 2h/3 distance from top.
4
Shear Stress is directly proportional to the moment of area above y about NA.
