Answer:
The distance of load from fulcrum is 5 m.
Explanation:
Given:
Mechanical advantage, MA = 0.4
Distance of force from fulcrum is, [tex]\textrm{Effort arm}=2\ m[/tex]
Distance of load from fulcrum is, [tex]\textrm{Load Arm}=?[/tex]
We know that, Mechanical advantage of a machine is the ratio of the effort arm and load arm.
So, Mechanical advantage is given as:
[tex]MA=\frac{\textrm{Effort Arm}}{\textrm{Load Arm}}\\\\0.4=\frac{2}{\textrm{Load Arm}}\\\\\textrm{Load Arm}=\frac{2}{0.4}=5\ m[/tex]
Therefore, the distance of load from fulcrum is 5 m.
