The sag developed in a bar of length ' 1 ', breath 'b' and thickness ' d ' when subjected to a load of ' w ' at center is (Y - Young's modulus of the material of the bar)

Options

  1. Aw^2 l^2 4 b d^2 Y
  2. Bw^3 b d^2 Y
  3. Cw l^3 4 b d^3 Y
  4. DNone of the above

Correct answer

D. None of the above

Step-by-step solution
