A multiple-threaded screw is designed in such a way for one complete rotation of screw advances to a distance of 5 times the pitch of the screw. If need to make the lead only up to 3 times of the pitch of screw then how many angles should we rotate the screw?

A multiple-threaded screw is designed in such a way for one complete rotation of screw advances to a distance of 5 times the pitch of the screw. If need to make the lead only up to 3 times of the pitch of screw then how many angles should we rotate the screw? Correct Answer 216 degrees

Given that, for one complete rotation the screw advances to a distance of 5 times the pitch of screw but we need only 3 times the pitch of the screw. Total rotation is 360 degrees. 360 x 3/5 = 216 degrees.
