A 1/4 inch 16 UNC bolt is tumed by a 8-inch wrench a robotic arm. 2 questions

A. What is the pitch of the bolt?

B. What is the IMA of the bolt being turned by the wrench?

need by end of day

A. The pitch of the bolt is 0.0625 inch

B. The IMA of the screw is approximately 12.57

Explanation:

A. The given information from the specification of the bolt are;

The major diameter, D, of the bolt = 1/4 inch

The number of threads per inch = 16 threads

The pitch of a bolt is he distance between each successive thread which is found by dividing a unit length by the number of threads of bolt in the unit length

Therefore;

The pitch of the bolt = 1 inch/(The number of threads per inch) = 1 inch/(16 threads per inch) = 0.0625 inch

The pitch, P, of the bolt = 0.0625 inch

B. The Ideal Mechanical Advantage (IMA) of the screw is given as follows;

IMA = The circumference of the screw/(The pitch of the screw)

IMA = π × D/P = π × 1/4 inch/(0.0625 inch) ≈ 12.57

The IMA ≈ 12.57
