Answer 4

story shear force acting in the x or y direction

Question 5

what else is the direct shear known as?

Answer 5

the shear not considering torsion

Question 6

what is torsional shear?

Answer 6

torsional shear is a force resulting from the rotation of the rigid diaphragm about center of rigidity
