Assignment:
Q1. Two forces P and Q are applied as shown at point A of a hook suport. Knowing that P=75 N and Q = 125 N. Determine by trigonometry (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.
Q2. Solve by trigonometry. Two forces are applied at point B of beam AB. Determine graphically the magnitude and direction of their resultant using (a) the parallelogram law, (b) the triangle rule.
Q3. The hydraulic cylinder BD exerts on member ABC a force P directerd along line BD. Knowing that P must have a 750-N component perpendicular to memeber ABC, determine (a) the magnitude of the force P, (b) it's compnenet parallel to ABC.
Q4. Determine the resultant of the three forces. X and Y
