Answer:
[tex]D.\ 20.4[/tex]
Explanation:
The simple machine in the attachment is a screw; so, I'll list the given parameters using related terms
Given
Radius of the screw (r) = 2.6m
Pitch (P) = 0.8m
Required
Calculate the Mechanical Advantage (M.A)
M.A is calculated as thus;
[tex]MA = \frac{2\pi r}{P}[/tex]
Substitute 2.6 for r; 0.8 for P and 3.14 for [tex]\pi[/tex]
[tex]MA = \frac{2\pi r}{P}[/tex]
[tex]MA = \frac{2 * 3..14 * 2.6}{0.8}[/tex]
[tex]MA = \frac{16.328}{0.8}[/tex]
[tex]M.A = 20.41[/tex]
From the list of given options, the approximated answer is D. 20.4
