A 550 ?? drawbridge has a hinge at one end and a cable attached to the other. It is stuck in a position where it makes an angle of 30° with the vertical. The cable pulling on the far end of the bridge is horizontal. Find the tension in the cable as well as the vertical and horizontal components of force from the hinge. Hint 1: Be careful with your ???? terms in this problem. Drawing a good picture should help. Hint 2: The length of the bridge will cancel out. Just use ?.
