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 simple machine of a screw driver?
A screwdriver is classified as a simple machine known as a lever. It consists of a long handle (the effort arm) and a shaft with a pointed tip that engages with the screw. When force is applied to the handle, the screwdriver rotates around the screw's axis, allowing it to turn the screw in or out. This mechanical advantage makes it easier to apply torque and drive screws into materials.
