How many revolutions of crank are needed to move the screw block 1 inch?

The number of revolutions needed to move a screw block 1 inch depends on the screw's lead, which is the distance the screw moves linearly with one full revolution of the crank. For instance, if the screw has a lead of 0.1 inches, it would take 10 revolutions to move the block 1 inch. To determine the exact number of revolutions, you would divide 1 inch by the lead of the screw.
