Because your hand can get a better grip and exert more torque or pressure.
i think a screw into a board a long screwdriver with a narrow handle
Every screwdriver has a handle. You hold the handle and turn it to tighten or loosen a screw. Sometimes your screw might be in a tight place that your hand can't get to such as inside of a car hood. You use a long reach screwdriver because the shaft above the handle is larger than a typical screwdriver. A typical screwdriver shaft is about 5 inches. A long reach screwdriver is bigger. Maybe 12 inches or 2 feet long. It's just a long screwdriver. I can't believe you would as this question
It's cheaper and lighter than a metal handle would be.
The mechanical advantage of a screwdriver is determined by the ratio of the length of the handle to the length of the shaft. For the 5 cm handle and 1 cm shaft, the mechanical advantage is 5:1, while the 3 cm handle with a 1 cm shaft has a mechanical advantage of 3:1. Therefore, the screwdriver with the 5 cm handle provides a greater mechanical advantage.
Long screw driver with a narrow handle would give the most torque, therefor it would be best It would also depend on the blade of the screw driver. The blade should fit well into the slot in the screw so if the long screw driver with the narrow handle had a small narrow blade that was too small for the screw then another one would be better.
1. A Long screw driver with a narrow handle would be better. Depending on the blade size, if the blade was smaller that would work better.ANS 2 - They both have particular uses, and both belong in a properly equipped tool box.
The metal part itself would be a conductor in theory but the handle would be an insulator as it is usually rubber or plastic.
Have you tryed to put a screwdriver in the "hole" where the door striker would go and as you pull the handle up push the screwdriver out. As if you were going throught the motions of the door opening but the screwdriver acts as the striker.
The ideal mechanical advantage (IMA) of a screwdriver is calculated by dividing the shaft radius by the handle radius. In this case, the IMA would be 4 mm (shaft radius) divided by 12 mm (handle radius), resulting in an IMA of 1/3 or approximately 0.33.
I would say anywhere from 1 to 20 lbs but i don't know for sure.
12 wire is bigger than 14 so nothing would happen, the bigger the wire the more current it can handle and the better it is.
The Effort (or moment) Arm of a screwdriver would be the largest radius of the handle frop the center, ie. the radius of a cylinder. You can use any unit vector along a radius, because they will all yield the same torque (or moment).
