The 6m boom AB has a fixed end A A steel cable is stretched

The 6m boom AB has a fixed end A. A steel cable is stretched from the free end B of the boom to a point C located on the certical wall. If the moment about A of the force exerted by the cable at B is (6315.79 kN-m)j + (3789.47 kN-m)k, determine the tension in cable BC

Solution

Tension is the pulling force acting on the bodywhen it is hanged to the objects and is denoted by T.

T= W+ma

where W is the weight of the body , m the mass of the body and a the accelaration.

W the weight is equal to mg

moment of a for ce is given by 6315.79+3789.47=10105.26

The tension T is = 10105.26x (6-2.4)= 36378.936 kN-m
