A uniform,horizontal beam of length 8.0 m and weight 14 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 60° with the horizontal.What is the tension in the cable needed to maintain the beam in equilibrium?
A) 8.1 N
B) 16.2 N
C) 97.0 N
D) 1.5 N
E) 56.6 N
