Mechanical Lab

Bring mechanical engineering concepts to life with Mechanical Lab. Explore 34 interactive virtual experiments, examine 10 animated 3D machines, and test your understanding with viva quizzes and numerical challenges—all offline.

Designed for mechanical engineering students, diploma learners, educators, and curious minds, Mechanical Lab connects engineering formulas with interactive calculations and visual explanations.

34 INTERACTIVE VIRTUAL LABS

Adjust inputs, see calculated results update instantly, and explore how changing a parameter affects an experiment. Each lab includes formulas, guided procedures, model assumptions, and graphs to support your learning.

Explore seven subject areas:

• Strength of Materials: tensile loading, beam deflection, shaft torsion, column buckling, and springs.

• Fluid Mechanics: Reynolds number, Bernoulli pressure changes, venturimeter discharge, hydrostatic pressure, pipe losses, and hydraulic power.

• Thermal Engineering: conduction, convection, radiation, heat exchangers, Carnot engines, Otto cycles, and compressor work.

• Machine Dynamics: gear trains, slider-crank motion, flywheel energy, vibration, and belt power transmission.

• Manufacturing: cutting speed, drilling time, milling material removal, and turning surface finish.

• Metrology: vernier caliper readings, micrometer readings, and thermal expansion.

• Energy Systems: pump affinity laws, engine brake power, and turbine output.

10 INTERACTIVE 3D MACHINES

Explore animated models of an engine, spur gear train, four-bar linkage, lathe, CNC milling machine, centrifugal pump, turbine rotor, universal testing machine, loaded beam, and shell-and-tube heat exchanger.

Rotate and zoom to inspect each model. Adjust animation speed, pause the motion, and switch to an exploded view to explore the assembly.

VIVA AND NUMERICAL PRACTICE

Build confidence with timed viva quizzes featuring 12 randomized multiple-choice questions and answer explanations. Practice applying engineering equations through calculation challenges with 10 numerical problems per attempt.

Review your answers and revisit your score history to follow your progress.

YOUR PERSONAL LAB NOTEBOOK

Save experiment inputs and calculated results for later review. Bookmark favorite labs, export observations as CSV files for spreadsheets, and generate experiment reports that you can print or save as PDF through Android’s print options.

Export and restore a local backup to keep your saved work.

LEARN OFFLINE

Use the labs, 3D models, and practice features without an internet connection. No account is required, and there are no ads. Your notebook and scores stay on your device unless you choose to export them. Choose a light, dark, or system theme for comfortable study.

Mechanical Lab uses simplified educational models. Results are calculated simulations, not physical measurements. Use it to support learning alongside classroom instruction and practical laboratory work.
