2. Many presses and other tools make use of the toggle, which is a pair of bars jointed together so as to form a very obtuse angle between them. When a 20 N force is exerted on the joint along the angle besector, the opposite ends of the bars may exert very larger forces on their restraints. If the angle at the joint is 170O , find the two horizontal forces necessary to hold the system in equilibrium. [Ans. 74N]
