Beams, trusses & load paths — how structures carry and transfer loads.
Move a section through a pin-and-roller beam test frame and trace applied loads into support reactions, shear jumps, bending moments and elastic deflection.
Load a slender compression specimen and compare elastic critical Euler load against imperfection amplification as end restraints and length change.
Inspect a wall-mounted cantilever, compare an ideal clamp with a rotational-spring root, and trace shear, hogging moment and tip deflection.
Load a five-joint Warren-style truss, solve the stiffness model, and trace tension/compression through all seven members and both bearings.
Compare two identical beam benches under the same loads, differing only in end restraint, and watch hogging moments and deflection change.
Follow vertical load and overturning moment through a column, spread footing and compression-only soil interface with a Winkler spring-bed model.
Load a simply supported reinforced-concrete beam and watch the cracked-section neutral axis, steel tension, concrete compression and deflection respond to bar count, diameter and span.
Apply an eccentric load to a bracket on a bolt group or two weld lines and resolve direct shear, torsional shear and reaction vectors.
Push three rigid floors with uniform or height-weighted forces and read story shear, drift, roof displacement and base overturning, including a soft first story.
