Design challenge — beam that passes deflection

Engineering · builds Math

Tune the beam so deflection stays within limits without wasting material. Both targets must be green.

Text description of this activity

Adjust span, depth, and load to keep a deflection index under 20 and a material index under 60.

Span12 m

Beam depth300 mm

Design load6 kN/m

Deflection index

0 in band

Target 0–20 · load × span³ ÷ depth³ (scaled)

Material index

0 in band

Target 0–60 · depth × span (scaled)

Readings update as you adjust each control.
