Answer:
The mechanical advantage of a lever can be calculated.
Explanation:
If the length of the effort arm and the length of the resistance arm are given we can calculated the mechanical advantage of a lever. It is also defined as the ratio of output force to the input force. Mathematically, it is given by :
[tex]MA=\dfrac{F_o}{F_i}[/tex]
Where
[tex]F_o[/tex] is the output force
[tex]F_i[/tex] is the input force
A lever is a simple machine in which there is a Plank that is free to free to rotate around a pivot. So, the correct option is (a) "the mechanical advantage of a lever can be calculated".
