Find the bending stress to which a screw of nominal diameter 22mm is subjected when the clamp exerts a force of 5kN acts on it. The screw is double threaded and pitch of screw is 5mm. Given: The coefficient of friction is 0.15. It is assumed operator exerts a force of 250N at the handle of length 275mm.
A. 123.45N/mm²
B. 132.54N/mm²
C. 142.54N/mm²
D. 124.45N/mm²
