Steps 1-3 Free Steps 4-6 Paid
STEP 1
Orient: solve equilibrium problems
Free
Establish a diagram-first workflow for solving unknown equilibrium forces.
Prompt preview will appear here.
Goal: build an equilibrium solution from a complete FBD rather than starting with algebra.
STEP 2
Conceptual grounding: build the equilibrium model
Free
Build the full sequence from FBD and axes to simultaneous equations and physical checks.
Prompt preview will appear here.
Goal: write and solve enough independent component equations for unknown forces.
STEP 3
Real-world connection: interpret balanced-force situations
Free
Apply the workflow to signs, ramps, cables, supports, and multiple unknowns.
Prompt preview will appear here.
Goal: check signs, units, limiting cases, and physical feasibility.
STEP 4
Check your understanding: diagnostic mini-quiz
Paid
Attempt each question before revealing the equilibrium reasoning.
Prompt preview will appear here.
Goal: identify and correct force-balance, axis, or system-choice errors before they become algebra errors.
STEP 5
Practice: solve increasingly rich equilibrium situations
Paid
Apply the model to equilibrium scenarios that grow in complexity.
Prompt preview will appear here.
Goal: produce clear, physically justified equilibrium solutions.
