A uniformly distributed load w (kN/m) is acting over the entire length of 8 m long cantilever beam. If the shear force at the midpoint of cantilever beam is 12 kN. What is the value of w? Correct Answer 3

Concept:

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

Cantilever beam:

Fx-x = wx

At x = 4 m (mid-point)

Fx-x = 12 kN

w × 4 = 12 kN

∴ w = 3 kN/m.
