Hand Tools

I believe that a screw driver is a third class lever ill update my answer later if wrong.

Yep, all you got to do is get some copper wire and a 9 volt battery, and wrap the wire repeatedly around the metal part of the screwdriver, and connect the wire one end to the positive terminal of the battery, the other to the negative end, then let it sit for an hour or two and the screwdriver will now be able to better grip screws and such.

A spud wrench is used to line up holes and tighten nuts on structural steel. Mostly used by iron workers. Iron workers sometimes use them to stand on while connecting iron.

A speed wrench ratchets back and forth.

You can't. It has to be a steel tip to withstand the torque.

The post between the handle and the tip that turns the screw.

A drill is a hand or electric powered device to bore holes.

It should be a 3/8 wrench. Correction 10MM and use a socket

Rather than using oil use a solution that drives out moisture and as you want it even drives out rust on tools. Such as WD-40.

yes, pliers are levers : )

the one that came with the car

That's a really amorphous question and I'm sure nobody has ever even thought about it seriously. In my case I would say 3/4 , but nobody really keeps count . We have many more important things in mind.

Saws that have a stiff piece of metal on the top edge of the blade. -Like a tenon saw.

A long screwdriver is handy when screws are deeply recessed or hard to access (such as in an engine bay reaching through the fan and under the starter motor where big human hands don't reach).

A long screwdriver can be easier to keep on the screw head. Picture a driver being held on a screw head in a wobbly hand where the driver stays on the head but the handle is rotating in an arc. Lets say the driver will slip out of the screw head if the hand wobbles more than 10 degrees off square to the screw head. For a long driver, this may need a wobble of 20mm, but the equivalent arc when using a stubby driver might result from only 5mm movement of the handle, needing a steadier hand.

If it's the "oil" drain plug, the size wrench is, better yet use a socket wrench=13mm.

Typically, no. Stainless steel is a very weak steel compared to other types. Your cheaper socket wrenches will typically be made out of chrome-vanadium. Higher-end models will use some form of tool steel.

Hand tools go back thousands of years and were invented as people needed them.

to hammer stuff

Hand tools are devices for performing work on a material or a physical system using only hands while the power toolsare tools powered by an electric motor Hand tools are devices for performing work on a material or a physical system using only hands while the power tools are tools powered by an electric motor
Hand tools use hands and power tools use power.
a power tool is an electric tool like a band saw or circular saw, a hand tool is a non electric one like a file or hammer
Hand tools you use your hands and power tools you use power like air or electricity

The wrench was invented by Daniel C. Stillsonof Cambridge, Massachusetts . October 12, 1869, U.S. patent #95,744 was issued to D.C. Stillson .

If it has a shaft of wood, metal or plastic and a head designed for striking -then it's some variety of hammer. There are dozens of kinds of hammer to perform many jobs.

All wrenches are steel .

Hammers are used for many things, banging in nails, pulling things apart with the claw, tapping bearings or rivets in, pounding out dents in metal and many other purposes.
