A 1 m rod of mass 100 kg is hanging from two in extensible support strings at its ends of equal lengths. If an another mass of 20 kg is placed on rod at a distance 30 cm from the left end, find the tension in the two support strings, if rod remains horizontal. Take g = 10m//s^(2) [560 N, 640 N]

A rigid mass less rod of length L is hinged at its one end a weight W is hung at a distance l(lt L) from this end. What is force P should be applied upwards at the other end so that the rod remains in equilibrium horizontally ? .

Shown in the figure is rigid and uniform one meter long rod AB held in horizontal position by two strings tied to its ends and attached to the ceiling . The rod is of mass 'm' and has another weight of mass 2 m hung at a distance of 75 cm from A . The tension in the string at A is :
