Objects in Equilibrium18.A uniform, horizontal beam of length 6.0 m and weight 120 N is attached at one end to a wall by a pinconnection (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 maintainthe beam in equilibrium?PTS: 1DIF:3TOP:8.2 Torque and the Two Conditions for Equilibrium | 8.3 The Center of Gravity | 8.4 Examples of

A 2.0-Nweight is suspended from the 10-cm position on the stick, another 2.0-N weight is suspended from the 50cm position, and a 3.0-N weight is suspended from the 60 cm position.
