The uniform rod shown below is held in place by the rope and wall. Suppose you know
the weight of the rod and all dimensions. Then you can solve a single equation for the force
exerted by the rope, provided you write expressions for the torques about the point:
A)
1

The pull
P
is just sufficient to keep the 14N block and the weightless pulleys in
equilibrium as shown. The tension
T
in the upper cable is:

The ideal mechanical advantage (i.e. the ratio of the weight
W
to the pull
P
for
equilibrium) of the combination of pulleys shown is:
