Investigate and explain the procedure by which mechanical engineers or motor mechanics fasten engine bolts using a ratchet.
Ratchet wrenches are a staple of all mechanics. With a good set of sockets, you can handle any bolt or nut on any vehicle. When you use a ratchet, you are able to tighten or loosen a bolt with minimal effort and often in a tight space where a regular wrench would have to be removed and replaced many times to get the same effect as a few swings of the ratchet handle. As long as your ratchet is in good working order, you'll be able to do the job quickly.
The ratchet works by applying leverage during the removal or tightening of a bolt.
