The mechanical advantage is 8/2 = 4.
Zero: the ramp cannot be shorter than the height to which it is suppose to reach. I suspect there is a missing decimal point.
5J because 10/2=5
5/20 = 1/4 or 0.25
Since the heights are the same, then the longer ramp.
1/5 = 0.2
Bigger is better no mater what situation. remember don't try this at home :)
The ideal mechanical advantage of the bar is 5.

The ideal mechanical advantage of a ramp is calculated by dividing the length of the ramp by the vertical height. In this case, the ideal mechanical advantage of the ramp is 120m (length) divided by 20m (height) which equals 6. Therefore, the ideal mechanical advantage of the ramp is 6.

a long and fat knife
204 inches
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
