How much force is needed to push a screw/nail into the wood is a function of the size of the surface area of the part of the screw/nail that you are trying to put in. This idea is described in the pressure function which says P=F/A The wood has a certain resistivity to deform but with enough Force (applied with a hammer/screwdriver) over a small enough Area (the bottom of the screw/nail) the Pressure will be enough to drive it through. your mom
Yes,screw can change the direction of force according to it's thread.A right hand thread means the screw will tighten for every right hand(clockwise) rotation.If it's thread is left hand the right hand rotation will loosen it and hence direction of force changes.
A screw may be considered an unlimited inclined plane. The force required to advance up the plane by using simple pressure, will depend of course upon the lubrication.
And if the force continues to be applied, the advance will continue until either the end of the plane is reached, or the limit of the force is reached.
the screw is allowed tp change the direction of the force
Friction originated from a screw is called the friction of a screw.
As you turn a screw with a screwdriver, the screw pushes into the material. Its a rotational force converting into a lateral or sideways force.
I don't think so.
No

I disagree

screw
moment of force (torque) i.e. the turning effect of a body(here,screw jack)= force applied X perpendicular distance of force from the axis of rotation. so in order to produce maximum turning effect of the screw jack by a force, the force is applied at a point on the body for which the distance from the axis is maximum so that the given force provides maximum torque to turn the screw jack. Thus,the screw jack is provided with a long arm.
No, it is not. In basic physics, torque is equal to force multipled (cross multiplication in vector terms) by distance (the moment arm).

First, because there is NO way to reduce the minimum amount of energy required to complete a task. You can't get something for nothing. But also because often it is easier to apply force (aka do work) in one direction and not another, like when using a pulley. You direct force down to lift a load up. It is also sometimes easier to apply a little force for a longer distance than apply and large force very quickly, like while pushing something up an inclined plane, wedge, or screw. Other times, it is necessary to exchange force for speed. Baseball players are very strong, but their arms cannot physically move as fast as they need to go to propel the ball, so they apply a lot of force in moving the bat, which moves very fast. The opposite is also true. In a screw driver, speed is not important but force is. Your hand moves the screw driver relatively quickly while the screw driver applies a larger force at a much slower rate.
A screw will have more holding force. As far as shear force, a screw is made from harder material and will break where a nail will bend.
None at all. You need energy if you apply a force AND you apply that force over a certain distance - work (which is basically transfer of mechanical energy) is equal to force x distance. (That's the simplified formula, for the special case of constant force, and if the direction of the movement is the same as the direction of the force.)
No.
screw
moment of force (torque) i.e. the turning effect of a body(here,screw jack)= force applied X perpendicular distance of force from the axis of rotation. so in order to produce maximum turning effect of the screw jack by a force, the force is applied at a point on the body for which the distance from the axis is maximum so that the given force provides maximum torque to turn the screw jack. Thus,the screw jack is provided with a long arm.

Yes. Erosion is weathering. It's can apply force but doesn't have to.
