The mechanical advantage of an inclined plane is the ratio of the inclined surface to the vertical height. Simple machines with greater mechanical advantage reduce the force required to lift a load. In which case is the effort required the LEAST?
A)
raising a 100 kg box to a height of 1 m using an inclined plane of length 5 m
B)
raising a 100 kg box to a height of 2 m using an inclined plane of length 6 m
C)
raising a 200 kg box to a height of 1 m using an inclined plane of length 4 m
D)
raising a 200 kg box to a height of 2 m using an inclined plane of length 8 m
