Solve the below problem:
Q: Three forces and a couple act on crank ABC. For P = 25 N and a = 40°,
(a) Determine the resultant of the given system of forces,
(b) Locate the point where the line of action of the resultant intersects a line drawn through point B and C.
(c) Locate the point where the line of action of the resultant intersects a line drawn through points A and B.
