Determinacy and indeterminacy refer to the stability and structural behavior of a beam or structure.
Determinacy: A beam is determinate when its reactions and internal forces can be calculated using equilibrium equations alone. In a determinate beam, the number of unknown support reactions is equal to the number of equilibrium equations that can be applied. Determinate beams are easier to analyze.
Indeterminacy: An indeterminate beam has more unknown support reactions than the available equilibrium equations can solve. It requires additional equations, such as compatibility equations or deformation equations, to determine the internal forces and reactions. Analyzing indeterminate beams is more complex and often involves techniques like the method of virtual work or the slope-deflection method.
The classification of beams as determinate or indeterminate depends on their support conditions and loading.
