Equilibrium in a single plane, statically determinate system Experimental investigation of the important principle of free vectors in statics Features - equilibrium conditions and support reactions of a leaning ladder Learning objectives/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 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 Specification [1] development of the static principle of "freeing" [2] full compensation of the support forces by cable forces [3] sliding clamp weight [4] determine the position of the clamp weight via built-in rule with millimetre scale [5] 2 supports (1x fixed bearing, 1x floating bearing) [6] 3 guide pulleys [7] storage system for parts [8] experiment setup in the SE 112 mounting frame Technical data Ladder - length: 650mm - weight: 2N - built-in rule, graduation: 1mm Clamp weight: 20N Weights - 3x 1N (hanger) - 9x 5N - 12x 1N Bearings - 2, clamped to mounting frame Tape measure - length: 3000mm, graduation: 1mm LxWxH: 1180x490x180mm (storage system) Total weight: approx. 28kg
