What is the mechanical advantage of the simple machine pictured? A. 8.3
B. 14.7
C. 1.9
D. 20.4

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;

Substitute 2.6 for r;  0.8 for P and 3.14 for

From the list of given options, the approximated answer is D. 20.4
