Question

a 3/8 inch bolt is being discussed. technician a says that the bolt diameter is 3/8 inch and could have 16 threads per inch. technician b says that the 3/8 bolt could have a tread pitch of 1.5m. who is correct? select one: a. a only b. b only c. both a and b d. neither a nor b

Explanation:

Step1: Analyze Technician A's statement

A \(3/8\) - inch bolt has a diameter of \(3/8\) inch. For standard bolts, a \(3/8\) - inch bolt can have 16 threads per inch. So Technician A is correct.

Step2: Analyze Technician B's statement

The pitch of a bolt is related to the number of threads per unit length. For metric bolts, the pitch is measured in millimeters. For a \(3/8\) - inch (imperial) bolt, we don't use the metric pitch measurement of \(1.5m\) (which is an incorrect unit for this context, should be \(mm\) if metric). So Technician B is incorrect.

Answer:

a. A only
