The 4-mm diameter cable BC is made of a steel with E= 200 GPa. Knowing that the maximum stress in the cable must not exceed 190 MPa and that the elongation of the cable must not exceed 6mm, find the maximum load P that can be applied as shown.
Base Length of AC= 4.0m
Height of AB = 6.0 m
Height from A to Load P= 3.5m
Load P to B= 2.5m
