What is the design procedure of screw jack?
First step: Find the core diameter of the screw second step: Find the torque required for lifting the screw
What is the design of screw jack?
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 is jack screw provided with long arm?
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.

What are the sources of error in case of screw jack?
Some potential sources of error in a screw jack include friction in the threads, misalignment of the components, deformation of the screw or load, and inaccurate torque measurement. These errors can affect the efficiency and precision of the screw jack's lifting capabilities. Regular maintenance and calibration can help reduce these errors.
What type of thread provides screw jack spindle?
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 :)
Is screw force the same as screw torque?
No, screw force and screw torque are not the same. Screw force refers to the axial force applied along the axis of the screw, while screw torque refers to the rotational force needed to tighten or loosen the screw. Torque is calculated by multiplying the force applied and the distance from the axis of rotation.
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.
Where is the torque screw on my chevy truck?
Give us more info like the year, model, engine and define "torque screw".
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.
To find the mechanical advantage load lost in friction of screw jack?
You would have to lift a given mass (m) a certain distance(h) and work out the amount of energy(work) this has taken using W=mgh, where g is acceleration due to gravity. Then you would have to use a torque metre to wind the jack , and using the number of turns needed to lift the weight, calculate the amount of work done, using E= torque x angle travelled(in radians). In an ideal frictionless jack the two figures would be the same. The difference between the two is the amount of energy lost to friction.The mechanical advantage you mention is related to the pitch of the screw or thread.That is,a fine thread pitch can lift more weight using only human force, but with a greater number of turns.I should also mention that in a diamond shaped,lever type jack, the mechanical advantage increases, and the torque required decreases, the higher the jack is extended. It becomes a little more complicated, involving vectors, angles, and maybe even calculus. Perhaps another poster could help here.
