A propped cantilever beam has one fixed support and one simple prop. What is its degree of static indeterminacy?
Correct answer: C. One
- A. Zero
- B. Two
- C. One
- D. Three
Explanation
A propped cantilever has four external reaction components, while planar equilibrium supplies only three independent equations. Therefore, one additional compatibility equation is required, making it indeterminate to degree one.

About Structural Analysis
Structural analysis determines how beams, frames, trusses and arches carry loads through reactions, shear forces, bending moments, axial forces and deflections. It covers free-body diagrams, equilibrium equations, determinacy, influence lines and methods such as slope deflection, moment distribution and virtual work, while distinguishing analysis of a structure from its design.
