Question

Imagine you wanted to build a clock with rotating minute and hour hands. Which of the following simple machine of

interlocking gears would you use? (1 point)
O a wheel and axle
O a lever
O an inclined plane
O a pulley

Answer 1

Wheel and axles

Step-by-step explanation:

Clocks run on a complex system of gear trains. This provides the energy to turn the hands of the clock. A high-ratio gear train gears the weight drum way up so that you don't have to rewind the clock very often. This somehow disengages, slips or ratchets the gear train so the clock can be rewound and set.
