Question

Working of bicycle and hand drill

Answer 1

Answer:

WORKING OF HAND DRILL:-

A hand drill is a manually operating tool that uses a crank to turn the drill chuck. The circular motion that's made when the user turns the crank is then converted into energy by moving the drill chuck in a similar circular motion, thanks to the pinion gears located on the main shaft.

WORKING OF BICYCLE:-

Bicycles turn energy created by our bodies into kinetic energy. ... A bicycle can convert up to 90 percent of a person's energy and movement into kinetic energy. This energy is then used to move the bike. The rider's balance and momentum help keep the bike stable while traveling along a path
