Answer:
6.5 cm
Explanation:
Mechanical advantage is a measure of efficiency or performance of a tool or machine in terms of force amplification which is done by the machine or tool. In simple terms, it measures that at what extent the applied force is increased with the help of tool or machine.
Mathematically, it is the ratio of force produced by the tool or machine to the force actually applied to the tool.
In terms of effort length and resistance length, it is calculated as -
Mechanical advantage = [tex]\frac{\textrm{Effort length}}{\textrm{Resistance length}}[/tex]
Thus, Mechanical advantage = [tex]\frac{26}{4}[/tex] = 6.5 cm.
