One end of a uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight W_1 is suspended from its lower end. If 'S' is the area of cross- section of the wire, then find the stress in the wire at height (3L//4) from its lower end?

Answer»

`((w_(1) + (3W//4) )/( S) )`
`( ( W+ ( 3w_(1) //4) )/( S) )`
`( w_(1) + w)/( 4)`
`( ( 3w_(1) + ( w//4) )/( S))`
