Here is the answer for the question – a uniform, horizontal beam of length 6.0 m and weight 120 N is attached at one end to a wall by a pin connection (so that it may rotate). A cable attached to the wall above the pin supports the opposite end. The cable makes an angle of 60with the horizontal. What is the tension in the cable needed to maintain the beam in equilibrium?. You’ll find the correct answer below
