In your question where as ask the man lift various loads with the same lever and the distance of the applied force from the fulcrum is 2m and the distance from the fulcorm to load is 0.5m.So the following are the answers to your questions:
a.mechanical advantage of the lever is 1
b..ideal mechanical advantage of the lever is 4
c.4

So, the required efficiency is 25%.

Given,

Distance of the applied force from the fulcrum=2.00 m

Distance from the fulcrum to the load =0.500 m

Mechanical advantage:

Mechanical advantage is a form of calculation that measures the amplified force taken by the mechanical system. It gives the ratio between the force applied to the load and the force needed to overcome the given force.

The formula of mechanical advantage is given as:

[tex]M_A=\frac{F_B}{F_A}[/tex]

Now, substituting the given values into the above formula,

[tex]M_A=\frac{0.500}{2}\\ =0.25[/tex]

Now, the ideal mechanical advantage will be,

[tex]effeciency=\frac{M_A}{I_A}\\ =\frac{0.25}{1} \\=25[/tex]
