PPSC CE SOM_SFD-Deflection

Statement 1: If the deflection at point A due to 5 KN load applied at B is 3 mm, then the deflection at B due to a unit load at A will be 15 mm.

Statement 2: Maxwell's reciprocal theorem states that deflection at a point A due to unit load at B will be equal to deflection at point B due to unit load at A

A cantilever beam of length L is subjected to a moment M at a distance equal to L/4 from the fixed end. The deflection at free end due to this moment will be

Assume flexural rigidity of the beam is EI throughout the length.

The amount of deflection in a beam depends upon

(i) The type of loading

(ii) Cross section of the beam

(iii) Modulus of elasticity of beam

(iv) Length of the member

A cantilever beam PQ of uniform flexural rigidity (EJ) is subjected to a concentrated moment M at R as shown in figure.
