a 2m crowbar is used to lift a load of 300kg. what force must be applied to one end of the crowbar when a stump acting at the fulcrum is placed under the crowbar 0.5m away from the end on which the load rests? neglect the weight of the crowbar
Answered by R_scott
the weight (force) of the load is ... 300 kg * g

the distance from the fulcrum to the lifting force is
... three times the distance from the fulcrum to the load

so the lifting force is at least 1/3 of the weight of the load
Answered by Henry2,
F1 = M*g = 300*9.8 = 2940 N.
F2 = ?

F1*d1 = F2*d2.
2940 * 0.5 = F2 * 1.5,
F2 = ?
