Screw jack is a non reversible machine,as it does not return to its original position even after the load is applied
Compound machines are things that are made up of 1 or more simple machines. A screw isn't made up of any simple machines unless you count the screw as a simple machine.
Yes. It is a screw action, which is a simple machine.
inclined plane and screw
Screw
yes
A reversible machine can operate in both directions, allowing for bidirectional movement, while a self-locking machine locks in place once power is removed, preventing unintentional movement. Reversible machines like electric motors can change the direction of rotation, whereas self-locking machines like a screw jack maintain their position without external forces.
the law of the machine is an expression which gives the relationship between the load on a machine and the applied effort
a reversible machine is a machine which is in itself a perpetual motion machine I am guessing.
Tak up a screw & jack then i will be a screw jack ahahahah
A screw jack is just that, a big screw in a base. As the screw is screwed out, it raises whatever it is under. A scissor jack that is in most new cars uses a screw to pull the jack together which causes it to raise up.
The effort is applied in the screw jack by turning the head of the screw. This then turns the jack a certain amount according to the pitch.

A screw-type scissors jack is an inclined plane. The threads on the screw is the plane wrapped around the shaft. The shaft is rotated by the means of a lever.An hydraulic (bottle) jack is usually a compound machine. It will have a screw in the piston to take up the slack and the hydraulic piston is actuated by a lever.An hydraulic wheeled floor jack will also be a compound machine. The handle that pumps the piston is a lever and the piston often pushes on a pantograph to raise the tongue. The pantograph is a set of levers.A buggy jack is a form of inclined plane.A bumper jack (the sort that consists of a post and a traveling mechanism) is an example of a lever.The last two examples are simple machines. See the links for pix.

Yes, a screw Jack Can be operated by electrically or manually.
Examples are Screwing in a screw - Unscrewing a screw Opening a door - Closing a door etc. Hope this helps
A synchronous machine is called a reversible machine because it can operate in both motor and generator modes. In motor mode, it converts electrical energy into mechanical energy to produce motion, while in generator mode, it converts mechanical energy into electrical energy. This ability to switch between modes makes it reversible.
