Three Dimensional Equilibrium Educational Equipment Mechanical Trainer Equipment

I.Overview
This equipment is for mechanical engineering department or mechanics engineering department in university, it’s for Theoretical and Applied Mechanics, Engineering Mechanics, Solid Mechanics major and other mechanics related department.
The equipment is used for studying the equilibrium of five concurrent and non-concurrent forces in a three dimensional system.
A rigid box frame has four swiveling pulleys at the top corners and leveling screws at the legs. Four cords, each with a load hanger outside the frame, pass over the pulleys and meet inside the frame concurrently or non-concurrently with an additional cord between two joints. A vertical load with a cord is applied at one of the joints. Each cord is marked out a 100 mm length. Two mirrors are attached on two adjacent side walls and transparent plates with transparent graph grids are attached on the other two side walls. By aligning each marked cord to the mirror, its coordinates in space can be measured.
Instruction manual is also included.
