A screw has 4 threads per centimeter and a circumference of 2 centimeters. The mechanical advantage of the screw is?
2 answers:
Answer:
Mechanical advantage = 8
Explanation:
It is given that,
A screw has 4 threads per centimeter.
The circumference of the screw, C = 2 cm = 0.02 m
The mechanical advantage of a screw is given by :
.............(1)
Pitch of a screw is defined as the number of threads per inch on the screw i.e.
Pitch = 1 / number of threads per inch or cm
or pitch = 1/4
MA = 8
Hence, the mechanical advantage of the screw is 8.
