Equilibrium in a Single Plane Model MT 120

Sci-tech Equilibrium in a Single Plane Model MT 120, 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.

Item Description

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.

Sci-tech Equilibrium in a Single Plane Model MT 120, 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.
