A hollow MSpipe is kept ona smoothstraight edge with the pipe mid pointsitting on it. A load “W’ Newtonsis applied at the ends which is keeping the pipe balanced in the horizontal condition. what is the safe maximum load ‘W’that can be applied withoutyielding the tube. Consider the self weight of the tube as ‘p’ $$\frac{N}{m}$$

Diameter of the pipe is 'd', Youngs modulus of pipe is E, Allowable yield stress is $$\sigma$$
