Does length of screwdriver matter?

Why do we prefer screw driver having long arms?

Torque or turning effect due to a force is maximum when r is maximum. We prefer to use a wrench with long arm because when the length of the arm(r) is long, the force (F) required to produce a given turning effect ( x ) is smaller. Hence, a nut can be unscrewed easily.

Why is a long screwdriver better than a short one?

If the screw in question is, say, inside a computer case, a longer screwdriver may let you get your forearm at a right angle to the shaft and thus as far away as possible; a short screwdriver, conversely, may restrict you so that not only is your arm at a shallower angle, but you might need to apply force with your …

Which is easier for turning a stuck screw a screwdriver with a large diameter or one with a long handle?

Longer, (read bigger) screwdrivers tend to have bigger handles. The lever you are using to loosen a screw is the radius of the handle. The bigger that is, the more leverage you have. You then put a lot of pressure on the driver against the screw, to avoid it riding out of the screw head, and use a spanner to turn it.

Why is it easy to open a screw with a screw driver?

Driving in screws is made easier if the handle is made larger in diameter than the screw head. In this way the small force exerted by the hand on the handle becomes a large pair of forces acting on the slot in the screw head.

Can you hammer in a screw?
