figure B has greater mechanical advantage
Explanation:
The mechanical advantage of a machine is the ratio between the output force and the input force.
For a ramp, the (ideal) mechanical advantage of a machine is also given by the formula
[tex]MA=\frac{L}{H}[/tex]
where
L is the lenght of the ramp
H is the height of the ramp
Therefore, in order to compare the mechanical advantage of these two ramps, we have to compare their ratio L/H.
By looking at the figure, we notice that:
- Figure A has greater height H and shorter length L
- Figure B has smaller height H and longer length L
This means that the ratio L/H is larger for figure B: therefore, figure B has greater mechanical advantage.
