1.	One end of a uniform wire of length .L. and mass .M. is attached rigidly to a point in the roof and a load of mass .m. is suspended from its lower end. If A is the area of corss - section of the wire then find the stress in the wire at height .x. from its lower end (x lt L)
Answer» SOLUTION : Tension in the STRING at point .P. is T=wt of load + wt of wire of LENGTH .x. `T = mg + M/L XG` stress at `P = T//A = (mg)/(A) + (Mxg)/(AL)`
