Question

The couple moment and the force in shear stress diagrams are divided to get the distance of the axis from the point of action of the force.

(a) True

(b) False

This question was addressed to me in quiz.

I'd like to ask this question from Shear Stress Diagram in portion Internal Forces of Engineering Mechanics

Answer 1

Right option is (a) True

The explanation is: The couple is the cross product of the force and the perpendicular distance between the forces. And if the division of the both is done than the resulting quantity is the distance only. But care must be taken that the product is the cross product and hence sine angle must be divided too to get the distance.
