Answer:
m = 0.5
Explanation:
Given that,
The length of the blade of scissors = 5 cm
The length of the handle = 2.5 cm
Here, effort arm is 2.5 cm and load arm is 5 cm. The mechanical advantage is the ratio of effort arm to the load arm as follows :
[tex]m=\dfrac{2.5}{5}\\\\m=0.5[/tex]
So, the ideal mechanical advantage of a pair of scissors is 0.5.
