7.5
15.5
30.0
60.0

Validate

Solution:

Concept:

Mechanical advantage (M.A) is the ratio of the load to the effort. For an ideal machine, it is also the ratio of the effort distance to the load distance.

Explanation:

From the machine in the diagram, the load distance is

15\ \mathrm{cm}

The effort distance is

0.5\ \mathrm{cm}

Therefore,

M.A = \frac{\text{load distance}}{\text{effort distance}}

M.A = \frac{15}{0.5}

M.A = 30.0

Answer:

30.0
