A 10m uniform beam, weighing 110N, is supported by two ropes at the ends, If a 380N person sits at 2.5m from the left end of the beam, what is the tension in each rope.

Question

Are you familiar with moments?

anonymous · Answer

No, just torque

anonymous · Answer

hmm, using torque to solve this will be slightly complex. Didn't you learn moments before learning about torque?

anonymous · Answer

No, this is Physics I and we were never taught moments

anonymous · Answer

I am not even sure if you'd use torque to solve for this problem

anonymous · Answer

okay...
since the beam is not moving,
Total torque =0.
$\Sigma \tau = \Sigma Fd$
|dw:1354412041449:dw|
in this case, as the beam is uniform, the center of weight is in the center. 
taking the torque at $T_1$
$2.5(380)+5(110)=10(T_2)$
you follow?
