4. A cable of length Lc supports a beam of length Lb, so that it is horizontal when the weight W is attached at the beam end. The principles of statics can be used to show that the tension force T in the cable is given by T=DLb2D2LbLcW where D is the distance of the cable attachment point to the beam pivot. If For the case where W=400N, Lb=5m, and Lb=3m, for D is in the range from 0.1
