A: Input side

9. Q 8: Which ramp would have a better Mechanical Advantage?
Ramp A
Ramp B
Height is
the same
A: Ramp A Longer ramps = less steep = better MA

10. Q 9: If the mechanical advantage of a machine is really low, what will the effort be like?

12. A: The ramp on the right gets LESS work done!
Q 11: If the two ramps are the same length, what is wrong with choosing the shorter height ramp to get the job done instead of the taller ramp?
Work = Force x Distance
