Question

If a beam is subjected to a constant bending moment along its length, then the shear force will
1) also have a constant value everywhere along its length
2) be zero at all sections along the beam
3) be maximum at the center and zero at the ends
4) be zero at the center and maximum at the ends

Answer 1

its answer is 1st but i m not sure

Answer 2

Answer:

If a beam is subjected to a constant bending moment along its length, then the shear force will also have a constant value everywhere along its length

correct answer is 1)also have a constant value everywhere along its length

Explanation:

The formula for shear stress is tau = F / A, where 'F' is the applied force on the member, and 'A' is the cross-sectional area of the member.

This theory also applies to triaxial states of stress which predicts that yielding will occur whenever one-half the algebraic difference between the maximum and minimum stress is equal to one-half the yield stress.
