LOADING
Question
A cantilever beam AB carries loading as shown in the following figure. Which of the following is the SFD for the beam ?
A.
B.
C.
D.
Answer ( Option A)

Solution

From the equilibrium of vertical forces,

RA = 2 kN

Shear Force on the Beam

At point A,          (SF)A = +2 kN

At point B,           (SF)B = +2 kN

A downward 2 kN at point B so SFD sudden drawdown 2 kN.

Shear force in portion BC = 0
