Challenge: two states, one linear law

Double the load, predict the effect on RFY, and demonstrate proportionality.

Challenge — Two states, one linear law

Modify the case to solve two load steps:

  • Load step 1: FY=-500 N, TIME=1.
  • Load step 2: FY=-1000 N, TIME=2.

You must keep both sets and demonstrate:

RFY₂ / RFY₁ = 2
RMZ₂ / RMZ₁ = 2

Each state must close force and moment with an error less than 0.5 %. The challenge is completed using a script, without selecting entities from the interface.

Predict before executing

If the reasons are not two, which hypothesis would you review first: linearity, substitution of the load, active set or support selection? Sort those checks before looking at the `.out`.

Conceptual explorer · not a solver

Explore force and moment equilibrium

Use this to make a prediction. Your MAPDL run and exported evidence remain the source of truth.

Transfer case

Transfer case: eccentrically loaded frame

Move the equilibrium audit to a frame where moment must close as well as force.

Execution cycle

  1. 1 Declare sign convention.
  2. 2 Predict reaction and moment.
  3. 3 Extract reaction sums.
  4. 4 Compare forces and moments separately.
Evidence to retain

Graduated hints

1 · Concept hint

Force and moment must close in a declared coordinate system.

2 · Command hint

Extract reactions and use a consistent geometric arm.

3 · Explained solution

Document denominators, signs, and tolerances separately.
