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 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
How does a trebuchet use force?
A trebuchet uses the force of gravity to propel its projectile. The counterweight falling creates kinetic energy, which is transferred to the arm of the trebuchet and then to the projectile, launching it forward. Additionally, the leverage provided by the long arm of the trebuchet amplifies this force.
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 an example of a complex machine using a pulley and a screw?
An example of a complex machine using a pulley and a screw is a crane. The pulley system allows for the lifting of heavy loads, while the screw mechanism is used to control the height and position of the crane's arm. Together, they enable the crane to efficiently move and position objects with precision.
