The shear force obtained at the midpoint of the cantilever beam is 12 kN. What is the value of uniformly distributed load w (kN/m) acting over the entire length, if the span length of the beam is 4 m? Correct Answer 6

Explanation:

Shear force at any section X-X is given by:

Cantilever beam:

FX-X = wx

At x = 2 m (mid-point)

FX-X = 12 kN

w × 2 = 12 kN

∴ w = 6 kN/m.
