equilibrium conditions and support reactions of a leaning ladder

Description:

• 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.

Learning Objective/Experiments:

• 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 1^st and 2^nd 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
