Problem 01 | Stress in Helical Spring

The helical spring shown is axially loaded with a compression force P equal to 5 kN. The mean diameter of the spring is 100 mm and the wire used is 10 mm as indicated in the figure.

  1. What is the shear stress at A?
  2. What is the shear stress at B?
  3. On diameter AB, locate the point of zero stress measured from C.
