A clear, neat, written solution is due at the beginning of class on Thursday 4/14/2016. A light pole of length L is at rest and makes an angle of with respect to the horizontal. The bottom end of the pole is hinged at the floor. A fish of mass ms hangs at rest from the top end of the pole. A horizontal cable is attached to the pole at a point L from the bottom of the pole. What is the mass of the fish if the magnitude of the tension in the horizontal cable is 25.0 N and a) 70.002 SHOW ALL WORK!

Solution

1. By balancing moments: T=70N

T*2/3*L*sin 70 = mg *L*cos 70

mg = T*2/3*sin 70 / cos 70

mg = 126.93 N

m = 12.95kg

2. Torque decreases, as T*1/3*L*sin 70 is less than T*2/3*L*sin 70
