Solve teh below problem:
Q: A force and a couple lying in the yz plane are applied to the end of a cantilevered wide-flange beam. This system is to be replaced with a single equivalent force.
(a) For θ =15°, determine the magnitude and the line of action of the equivalent force,
(b) Determine the value of θ if the line of action of the equivalent force intersects a line drawn through points B and C 40 mm above C.
