Question

A bolt has 16 1/2 turns per inch. How many turns would be in 2 1/2 inches of thread?

Answer 1

49 and 1/2 turns. Hope this helps.

Answer 2

We know that one inch has 16.5 turns.
To know the number of turns in 2.5 inches of thread, we will simply do a cross multiplication as follows:
number of turns = (2.5 x 16.5) / 1 = 41.25 turns
