Waypoint Mentor

An engineering tutor that knows statics from thermo.

Made for engineering coursework. Talk through a beam, a truss, a cycle or a circuit and the tutor sets up the free-body diagram, writes the equilibrium equations, carries units through every line and checks the answer makes physical sense.

How do I find the support reactions on a simply supported beam?
Take moments about one support so one unknown drops out, then use vertical equilibrium for the other.

Given: simply supported beam, L=6L = 6 m, point load P=10P = 10 kN at a=2a = 2 m from A.

1. Moments about A (anticlockwise positive):

RB⋅L−P⋅a=0⇒RB=PaL=10×26=3.33 kNR_B \cdot L - P \cdot a = 0 \quad\Rightarrow\quad R_B = \frac{P a}{L} = \frac{10 \times 2}{6} = 3.33\ \text{kN}

2. Vertical equilibrium:

RA=P−RB=10−3.33=6.67 kNR_A = P - R_B = 10 - 3.33 = 6.67\ \text{kN}

Check: the load is closer to A, so A should carry more. It does.

How the engineering tutor helps

Method first

Free-body diagram, sign convention, equations, solve, check: the same method your lecturer marks against.

Hand-checked simulations

Beam reactions, shear and moment diagrams, trusses and torsion simulations, each checked before students see it.

Your course, your notation

On Plus, upload your lecture slides and the tutor uses your course's notation and examples.

Engineering topics it covers

  • Statics and equilibrium
  • Beams, shear and moment diagrams
  • Trusses
  • Mechanics of materials
  • Dynamics and vibrations
  • Thermodynamics
  • Fluid mechanics
  • Electrical circuits

Not on the list? Ask anyway: it covers any engineering topic, and on Plus it answers from your own uploaded course notes.

How a session works

  1. 1.

    Ask out loud or type

    Press Start talking and talk like you would to a tutor, or type your question. You can interrupt it any time.

  2. 2.

    Watch it on the whiteboard

    The working appears one step at a time. Say "yes" to move on, or ask for a step to be explained another way.

  3. 3.

    Check you've got it

    It ends with a quick question to check, and remembers what you found hard for next time.

Questions about the AI engineering tutor

Can I talk to it out loud?

Yes. Press Start talking and just talk, like a call with a tutor. You can interrupt it mid-sentence, and it puts the working on a whiteboard while it explains. Free accounts get 10 voice minutes a month, with no card needed.

Which engineering subjects does it cover?

Statics, dynamics, mechanics of materials, thermodynamics, fluid mechanics, heat transfer, electrical circuits, signals and control, and the maths behind them.

Does it draw free-body and bending moment diagrams?

Yes. It draws diagrams on the whiteboard and can open interactive simulations, like a beam where you drag the load and watch the shear and moment diagrams change.
