First step: Find the core diameter of the screw second step: Find the torque required for lifting the screw
Tak up a screw & jack then i will be a screw jack ahahahah
Jack Screw is a sistem for dissasembling. The diference is that the flange has threathed holes where a bolt is installed.
There's a relief/bleed screw at the bottom of the jack. Loosen this screw two full turns. Then, using the handle, pump the jack between ten and twenty full strokes. Retighten the relief screw.

in case of simple screw jack it's single start square thread in case of worm geared screw jack it's double start square thread double start gives greater speed but requires more torque ,hence worm geared :)
it is the creation of an idea to analyze forces,torque's and synthesis of a screw jack to perform work or lift load with maximum efficiency.the optimum and short procedure to design the screw jack includes only two steps are as follows:- 1.determine the diameter of core of a screw. 2.determine the torque required to lift the load.
why design a screw jack? there are all different types of screw jacks available screw jacks are used on vehicles, other screw jacks are used in construction,and any other lifting application that you can thick of.
Design of the screw : procedure core diameter of the screw is determined using allowable stress and the given load. Using the core diameter, the rest of the diameters and the pitch will be determined. -As screw is subjected to twisting moment, higher value of screw is selected. Select the dimension of dc w.r.t pitch Mean diameter d= do- p/2
Cast iron is the material often used to design screw jacks because of its strength.

what is the procedure for design of a linker ?
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.
Yes, a screw Jack Can be operated by electrically or manually.

Take top cover off of jack and there should be a rubber plug or a single screw that you take out to fill jack .
