Answer 2

the only formula I could was mechanical advantage = circumference/pitch where pitch is the distance between ridge things on the screw (1.3 mm)

so treat the screw as a circle with radius 2.1mm and pitch 1.3 mm

Answer 3

so 2.1/1.3

Answer 4

circumference = ?

Answer 5

i got 1.6

Answer 6

4.2

Answer 7

what is the circumference of the screw if the radius is 2.1?

Answer 8

13.19

Answer 9

good then divide that by the pitch

Answer 10

10.1

Answer 11

yeah that's what I got too well done
