Mechanical advantage of the ramp is 5
Explanation:
The Mechanical Advantage (MA) of a simple machine represents the factor of multiplication of the input force applied in the machine; it represents the mechanical advantage of the machine taking into account the energy losses due to internal frictional forces.
It is given by
[tex]MA=\frac{Load}{Effort}[/tex]
where
Load is the force in output, which is the weight of the object moved
Effort is the input force applied to move the object
For the ramp in this problem, we have:
Load = 100 N
Effort = 20 N
Therefore, the mechanical advantage is
[tex]MA=\frac{100}{20}=5[/tex]
