In order to lift a 300 newton object two meters using a leve

In order to lift a 300 newton object two meters using a lever, a force of 100 newtons must be moved through a distance of eight meters match the following quantities:

effort_________

IMA________

AMA___

restistance distance ________m

efficiency _________

Solution

1. Effort 100N

2. IMA= F_out/F_in = 300/100= 3

3. AMA = efficiency*IMA = 0.75*3 = 2.25

4. Resistance distance- 2m

5. Efficiency= Output work/Input work = (300*2)/(100*8) = 75 %
