The rigid bar AD is supported by two steel wires, one of length 15 in and the other of length 8 in, and 1/16-in diameter with a modulus of 29e6 psi and a pin at bracket D. Assume that the wires were initially taut before load P was applied... a. Determine the additional tension in each wire when the 120-1b load P is applied at B b. Determine the deflection at point B C. Discuss why the wires are assumed to be taut (i. e. based on the information provided, what is your rationale for the assumption)
