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.


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.

How does a jack screw work?

A jack screw is a type of mechanical device used to lift heavy loads. It works by rotating a threaded rod through a threaded hole in a stationary nut, which causes the nut to move along the rod. As the nut moves, it applies force to the object being lifted, allowing for controlled and precise lifting operations.
