The derrick shown supports a 2000-kg crate. It is held by a ball-andsocket joint at A and by two cables attached at D and E. Knowing that the derrick stands in a vertical plane forming an angle f with the xy plane, write a computer program that can be used to calculate the tension in each cable for values of ∅ from 0 to 60° using 5° increments. Using appropriate smaller increments, determine the value of f for which the tension in cable BE is maximum.
