AE & JE CE Quiz Strength of Material Booster Quiz-1

Design of shaft made of brittle materials is based on

During strain hardening:

The variation of BM in the portion of a beam carrying uniformly varying load is

A cantilever beam fixed at left and carries a udl w/unit length over the left half portion and a point load W at the free end. If L is the length of the beam, the bending moment at fixed end is:

In case of biaxial stresses, the maximum value of shear stress is

The bending moment on a section of a beam is maximum where shearing force is

The relationship between maximum bending stress (σ) offered by a section, moment of resistance (M) and section modulus (Z) is given by

Shear stress on a principal plane is

Ability of a material to absorb energy within the elastic range:

Principal stresses at a point in a plane stressed element are = = 500 N/mm². Normal stress on the plane inclined at 45° to the x-axis will be
