please is urgent The 7.8m steel I-beam has a mass of 800kg and is lifted into position by applying a force P on the trolley to which the lower end B is secured. Cable AC is tied center of the beam and is horizontal when B is exactly below C. Determine, in function of x, the force P needed to maintain equilibrium from x=0 to the value of x at which A' lies exactly below C. Find the maximum value of P and the corresponding value of x.
