Homework Statement
A 60 kg man hangs one meter from the end of an 8 m, 100 kg beam. A steel cable is attached to the end of the beam near the man, and the opposite end is supported by a frictionless pin (or a hinge). The system is originally at rest. The cable makes a 35 degree angle between the horizontal and the hypotenuse.
Find the tension in the cable.
Homework Equations
T=Fd
Net Force=0
Net Torque=0
The Attempt at a Solution
I draw my free body diagram and get the weight force of the steel rod being exerted at 4 m. I get the hanging man’s normal force at 7 m. I get a tension force at 35 degrees on one end, and then I get a vertical and horizontal normal force from the pin on the other side.
Horizontal forces
Pin(x)-Cable(x)=0
Vertical forces
Pin(y) + Cable(y) -Beam- Man=0
I am having trouble incorporating torque into this problem and I know I need to. Where should I place my reference frame to find torque?
