Introduction to Statics Laboratory
Five mechanics-foundation models with explicit units, assumptions, and independent calculations.
Compare balanced and unbalanced collinear force systems and inspect the acceleration boundary.
Model scope and verification
Scope: Educational mechanics models using ideal forces, rigid geometry where stated, and explicit SI/US conversion constants. Idealization thresholds are screening guidance, not universal design limits.
Acceptance check: Check dimensions first, then verify force balance, W = mg, exact conversion factors, the stated screening thresholds, or Cartesian component addition. Vector labels use a fixed legend so coincident and zero-resultant cases remain readable.
