SOLVER-DRIVEN STATIC EQUILIBRIUM3 members · 3 joints · pin A / roller B

MEMBER INSPECTOR

Inspect calculated axial forces

Static model · no fabricated motion

Axial member force-8.49 kN

Axial action (force sign)Compression

Diagonal inclination45.0°

Selected member length4.24 m

Estimated axial stress σ-8.49 MPa

Estimated axial strain ε-4.243e-5

Member extension ΔL-0.1800 mm

Crown vertical shift-0.3446 mm

Equilibrium checkRₐ + Rᵦ − P = 0.000000 kNBlue: tension · pink: compression. Axial stress assumes each member has A =1000 mm² and E = 200 GPa. The crown displacement is a small-strain linear elastic compatibility estimate; its deformation is NOT drawn at true scale. Neither stresses nor deflection establish buckling capacity, yield, joint design or structural safety.

CROSS-SECTION INSPECTOR

Read shear, moment and deflection at any x

Displacement curve visually exaggerated

Measurement positionx = 3.00 m (50% of span)

Local shear V(x)-4.00 kN

Bending moment M(x)21.00 kN·m

Elastic deflection δ(x)43.594 mm

Flexural rigidity EI1.60e+6 N·m²

Nominal bending stress at x131.25 MPa

Maximum |bending stress|131.25 MPa

Equilibrium checkRₐ + Rᵦ − P − wL = 0.000000 kNPositive deflection is downward. At a concentrated load, shear is discontinuous; the reported value is the right-hand limit. Shear left-hand value: 4.00 kN.Nominal bending stress σ = M c / I with an assumed extreme-fiber distance c = 50.0 mm. The supplied section dimension and second moment I must describe the same real cross-section; otherwise the stress is not physically interpretable. Elastic linear bending only: no shear-strength, yield, stability, fatigue, code capacity or safety-factor prediction.
