Which of three classe of lever is a screw car jack under?
If you wrap an inclined plane around a small circle what you will end up with is a screw jack
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
Why is jack screw provided with a 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.
Is screw jack reversible machine?
Screw jack is a non reversible machine,as it does not return to its original position even after the load is applied
How does a screw jack work to lift heavy loads?
A screw jack works by using a threaded screw to lift heavy loads. When the screw is turned, it moves up or down, causing the jack to raise or lower the load. The mechanical advantage of the screw thread allows for the lifting of heavy objects with less effort.

Why threads are provided in simple screw jack Give reasons?
Threads are provided in a simple screw jack to allow the movement to be calculated to a certain distance or height and to allow for less effort in lift.
What is mechanical advantage of screw Jack?
You divide the pitch of the jack's screw into a length equal to the distance traveled by the end of the Jack's lever around the circumference of a circle having a radius equal to the jack's lever. Elliott
Is a screw a first class lever?
Yes, a screw can be considered a first-class lever. The effort (force applied to turn the screw) acts on the handle, the fulcrum is at the screw's axis, and the load (resistance being overcome) is the material being drilled through.
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.
Can you use a screw Jack electrically?
Yes, a screw Jack Can be operated by electrically or manually.
