COMPONENTS OF FORCE
rope and weight
APPARATUS
29 lb. weight 202-04-E
rope 202-04-E
hook 202-04-E
stool
 202
DESCRIPTION
Two teams of four students each, pulling opposite ends of the rope, are needed to lift the weight off the stool.
2T sin θ= W
T = W/(2 sin θ)
T may be made arbitrarily large by making θ arbitrarily small
force vectors
NOTES
One variation is to have two strong people try to stretch out rope horizontally while a small person pushes the middle of the rope to the floor.
