Here is how the problem was reasoned through according to the book:
"The axis of rotation is the point where the rope attached to the board. The hanging weight creates a counter-clockwise torque equal to 3kg x 0.2m. The wight of the board creates a clockwise torque at the distance from the rope...
Hi All,
I'm confused with a particular question and I'm not entirely sure how the answer was derived.
A one-meter board with uniform density hangs in static equilibrium from a rope with tension T--The rope is connected .2m from the left end. A weight of 3kg hangs from the left end of the...
