Engineering AI Homework Helper from assumptions up
Name the principle, list what is known and what is assumed, then solve with units and ask whether the answer is physically reasonable — the way engineers work.

Disciplines and the principle behind each
Statics and dynamics
Equilibrium, Newton's second law, work–energy and impulse–momentum for particles and rigid bodies.
Circuits
Ohm's law, Kirchhoff's current and voltage laws, equivalent resistance and simple RC circuits.
Thermodynamics
The first law as an energy balance, ideal gas relations and the efficiency of a cycle.
Fluids
Continuity, Bernoulli's equation, pressure at depth and the basics of head loss.
Materials
Stress as force ÷ area, strain, Young's modulus and the elastic region of a stress–strain curve.
Engineering math
Unit conversions, significant figures and turning a word problem into equations.
Worked example: flow from a wide pipe into a narrow one
Principle: for an incompressible fluid in steady flow, the volume flow rate is the same at every cross-section, so A₁v₁ = A₂v₂. Assumptions: water is incompressible, the flow is steady, and each velocity is the average across its section.
Since A = πd²/4, the ratio of areas is (d₁/d₂)² = (5 cm ÷ 2.5 cm)² = 4. Then v₂ = v₁ × A₁/A₂ = 2 m/s × 4 = 8 m/s.
Reasonableness: halving the diameter quarters the area, so the water has to move four times faster to carry the same flow. The result has units of m/s, a velocity, and faster flow in the narrower pipe matches what you see when you pinch a garden hose.
How engineering students use it
Give the full problem
Include the givens, units and any figure. A photo of the problem (PNG, JPG or WebP, up to 5 MB) is transcribed before solving.
Choose depth and style
College / university is preselected. Pick a patient tutor for a new topic or exam revision for a quick refresher.
Read the assumptions
Before the math, see which simplifications were made — steady flow, ideal gas, no friction — and whether your problem allows them.
Verify and extend
Do the dimension check, attempt the practice problem and carry on in AI Chat with a follow-up.
What each answer includes
Frequently asked questions
It is set up for statics, dynamics, circuits, thermodynamics, fluids and materials. When a question is really pure math or physics, it still helps and says which subject the question belongs to.
No. It explains principles and works through textbook-style problems for learning. Open-ended design decisions, your own test data and project reports need your judgment and your instructor's guidance.
It does not run software or simulations. It reasons through the equations in text and can explain how you would set them up in your own tools.
On a Pro plan it's included* (*fair use: up to 300 runs a day across the writing, study and code tools). Without a plan, a problem uses 2 credits, or 3 with an image attached. Before signing in, you can preview the first part of an answer for free.
It depends on your course. Use the solutions to learn the approach and compare them with your attempt, and follow your instructor's policy on AI assistance.
Each answer includes a dimension and reasonableness check, but AI can still make errors in algebra or unit conversions. Recheck the key steps yourself.
