Answer:
A. The pitch of the bolt is 0.0625 inch
B. The IMA of the screw is approximately 12.57
Step-by-step 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
