1) A rope 5m is fastened to two hooks 4m apart on a horizontal ceiling. To the rope is attached a 10kg mass so that the segment of the rope are 3.0m and 2.0m.Compute the tension in the string. 2) A uniform pole 7m long weighing 10kg is supported by a boy 2m from one end and a man 3m from the other end. At what point must 20kg weight be attached so that the man would support thrice as much weight as the buy 3)A man carries a load of mass 2.6kg from one end of a uniform pole 100cm which has a mass 0.4kg the pole rests on his shoulder at a point 60cm from the load he holds it at the other hand what vertical force must be applied by his hand and what is the force on his shoulder. Rule of equilibrium under parallel complanor force Total downward forces = total upward forces total anticlockwise moment= total clockwise moment moment= force x perpendicular distance to line of action.
