For the hook support of Problem 2.3, using trigonometry and knowing that the magnitude of P is 25 lb, determine

(a) The required magnitude of the force Q if the resultant R of the two forces applied at A is to be vertical

(b) The corresponding magnitude of R. Problem 2.3: Two forces P and Q are applied as shown at point A of a hook support. Knowing that P = 15 lb and Q = 25 lb, determine graphically the magnitude and direction of their resultant using (a) the parallelogram law, (b) the triangle rule.
