What is the mechanical advantage of the screw shown below?
algol13

Answer:

C. 8.0

Step-by-step explanation:

The mechanical advantage is got from dividing the circumference of the shaft by the pitch of the screw.

Therefore, the circumference= 2πr

                                                  =2×π×2.3mm

                                                   =14.45mm

Mechanical advantage=14.45mm/1.8mm

=8.03
