Answer 2

M.A = 8

Step-by-step explanation:

Given the following data;

Circumference = 2cm

Number of threads = 4

To find the mechanical advantage (M.A);

`Mechanical \; advantage = \frac {Circumference}{Pitch}`

But,
`Pitch = \frac {1}{number \; of \; threads}`

`Pitch = \frac {1}{4}`

Pitch = 0.25

Substituting the values into the equation, we have;

`M.A = \frac {2}{0.25}`

M.A = 8

Therefore, the mechanical advantage of the screw is 8.
