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

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
