Question

The camshaft brocket has twice as many teeth as the crankshaft. How many times will the camshaft brocket rotate if the crankshaft rotates once?

1) Once
2) Twice
3) Three times
4) Four times

Answer 1

The camshaft sprocket will rotate once for every complete rotation of the crankshaft sprocket if it has twice as many teeth.

Step-by-step explanation:

If the camshaft sprocket has twice as many teeth as the crankshaft sprocket, then for every complete revolution that the crankshaft makes, the camshaft will rotate half as many times. This is because gears with more teeth turn slower than gears with fewer teeth when they are meshed together. Specifically, if the crankshaft rotates once, the camshaft sprocket, having twice as many teeth, will rotate only once because it has to cover twice the distance (in terms of teeth) to make one complete turn.
