Why is a screw a simple machine and not a compound machine?
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.
Is a jar lid a simple machine?
Yes. It is a screw action, which is a simple machine.
What simple machine use to hold two boards together?
Screw
What type of simple machine is a jar lid?
inclined plane and screw
Is a car jack a simple machine?
yes
What are some examples of an winding inclined plane machine?
A screw jack is an example.
What is Law of machine of simple screw jack?
the law of the machine is an expression which gives the relationship between the load on a machine and the applied effort
How do you prove conservation of energy If you read Feynman's Lectures ch 4 what is meant by the whole reversible machine experiment?
a reversible machine is a machine which is in itself a perpetual motion machine I am guessing.
What is difference between reversible machine and self locking machine?
Self locking machine has efficiency less than 50% but reversible machines has efficiency more than 50%
What is manufacturing process for compound screw jack?
Tak up a screw & jack then i will be a screw jack ahahahah
How screw Jack works?
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.
How is the effort applied in the screw jack?
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.
What type of machine is a cork screw?
Screw
What is simple machine is jack?
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.
