What is the mechanical advantage of a wheel barrel that is 4cm long with 0.75m between the wheel and the center of the load?

The mechanical advantage = 4/75

Explanation:

A wheel barrel is a second class as the effort is placed further from the point of fulcrum than the point of action of the load

The parameters given are;

Length of wheel barrel = 4 cm

Distance between wheel and center of load = 0.75 m

Therefore, we have the mechanical advantage, MA given as follows;

= Output force

= Input force

= Distance from output force =  0.75 m

= Distance from input force = 4 cm = 0.04 m

Therefore;

The mechanical advantage MA = 4/75 = 0.0533

Therefore, more force (75/4 × the load) will be required to lift a given load.
