Screw Jack: The Mechanism Behind Tightening and Supporting a Shoring System

What type of jack is used to tighten and support a shoring/stabilizing system?

A. Screw jack
B. Hydraulic jack
C. Trench screw jack
D. Ratchet-lever jack

Answer:

The Screw Jack is the jack type which is used to tighten and support a shoring/stabilizing system.

The type of jack that is operated by using the jack to tighten and support a shoring/stabilizing system is a Screw Jack. A screw jack uses a mechanism similar to a screw, rotating it to create an axial force. Unlike a Hydraulic Jack which uses an incompressible fluid to distribute force and is commonly used to lift heavy loads such as automobiles, the screw jack is used for applications where stabilization and support in a vertical position is needed. It uses the principle of conversion of rotational motion into linear motion to provide stability and firm support to various structures.
