Asked by Georgia
Ms. Sue could you please explain this to me. Imagine you need to deliver a piano over three steps. A longer ramp translates into less force necessary to raise the piano's height than a shorter ramp would require. Calculate the percentage smaller a force would be required using an 2.8m long ramp compared to a 0.9m ramp?

Work=F*d
So,
Work=F1*2.8m
Work=F2*0.9m
F2*2.8m=F1*0.9m
F2/F1=0.9m/2.8m
(0.9m/2.8m)*100=32.4%
F2 is 32.4% of F1
So,
Work=F1*2.8m
Work=F2*0.9m
F2*2.8m=F1*0.9m
F2/F1=0.9m/2.8m
(0.9m/2.8m)*100=32.4%
F2 is 32.4% of F1

The first post probably wasn't that clear
F1=force of 2.8m ramp
F2=force of 0.9m ramp
Work=F*d
So,
Work=F1*2.8m
Work=F2*0.9m
F1*2.8m=F2*0.9m
F1/F2=0.9m/2.8m
(0.9m/2.8m)*100=32.4%
F1is 32.4% of F2
F1=force of 2.8m ramp
F2=force of 0.9m ramp
Work=F*d
So,
Work=F1*2.8m
Work=F2*0.9m
F1*2.8m=F2*0.9m
F1/F2=0.9m/2.8m
(0.9m/2.8m)*100=32.4%
F1is 32.4% of F2
