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)

A mass of 2.9 kg is suspended from a string of length 50 cm and is at rest. Another body of mass 100 g, which is moving horizontally with a velocity of 150 m//s strikes and sticks to it. Subsequently when the string makes an angle of 60^@ with the vertical, the tension in the string is (g = 10 m//s^(2) )
