Max Shear of a Beam Under Uniform Load

Easyshearuniform load
For the same beam - simply supported, L = 8 m, w = 10 kN/m - what is the maximum shear force?
  1. A40 kN
  2. B80 kN
  3. C20 kN
  4. D10 kN
Show solution

Answer: A. 40 kN

Vmax occurs at the supports and equals each reaction: V = w L / 2 = 10 · 8 / 2 = 40 kN. Shear drops linearly to zero at midspan, which is where the moment peaks. 80 kN is the total load.
