a bar of length l and uniform density is held horizontally against a wall by a
pivot at one end and a rope of tension t which pulls up and to the left
making an angle with the vertical wall. the rope is attached to the bar at
a distance i = l from the wall. a mass m is resting at the end of the bar.
if the bar has total mass 2.3kg, the mass m=2.0kg, and the rope makes an
angle of 32.6' with the wall, what is the magnitude of the force exerted on
the bar by the pivot |fpivot| answer in newtons (n).
