Features
Equilibrium conditions and support reactions of a leaning ladder 

The principle of “freeing” in engineering mechanics allows forces and moments acting on a body to be  made visible. In this process, a body or a system such as a bar are virtually removed from the  environment. All forces acting on the body or on the system are replaced by standardized symbols.

This results in a simplified model of the body or system, which clearly demonstrates the relationships  between forces and moments. 
 
Tesca Equilibrium in a Single Plane, demonstrates the principle of “freeing”,  which refers to establishing static equilibrium. The experiment uses a model of a ladder with a sliding  clamp weight. 
 
The top support is designed as a movable support and the bottom one as a fixed support. The real  effective support forces can be fully compensated by applying cable forces in the x and y directions.  The ladder is in a state of equilibrium without changing the angular position and without the need for  structural support. The ladder is “free”. For students, the result is a convincing example for the  principle of “freeing” in statics.  

The parts of the experiment are clearly laid out and securely housed in a storage system.
