Answer:
M.A = 8
Explanation:
Given the following data;
Circumference = 2cm
Number of threads = 4
To find the mechanical advantage (M.A);
[tex] Mechanical \; advantage = \frac {Circumference}{Pitch} [/tex]
But, [tex] Pitch = \frac {1}{number \; of \; threads} [/tex]
[tex] Pitch = \frac {1}{4} [/tex]
Pitch = 0.25
Substituting the values into the equation, we have;
[tex] M.A = \frac {2}{0.25} [/tex]
M.A = 8
Therefore, the mechanical advantage of the screw is 8.
