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 standardised symbols.
- This results in a simplified model of the body or system, which clearly demonstrates the relationships between forces and moments.
- In the experiment SE 110.53, we demonstrate 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.
- The entire experimental setup is constructed in the SE 112mounting frame.
- experimental development of the core principle of “freeing” in statics
- calculation of the support forces for a given position of the clamp weight and for a known angle of inclination
- application of the 1st and 2nd equilibrium conditions in statics and full compensation of the support forces by cable forces
- how does the clamp weight position affect the support forces?
- how the angle of inclination affects the support forces
