Engineering Calculators for Students

A problem-focused study hub for checking formulas, units and worked engineering calculations across structures, electrical, fluids, HVAC, materials and automotive topics.

Structures & mechanics

Beam deflection Bending stress Shear force & bending moment Steel column

Electrical

Voltage drop Transformer sizing Motor current & breaker DC cable sizing

Fluids & HVAC

Pipe pressure drop Pump power Cooling load Duct size

Materials & civil

Density & unit weight Concrete quantity Asphalt tonnage Steel beam sizing

Automotive

Engine displacement Compression ratio Horsepower & torque Bore & stroke

How to use these tools for study

Start by writing the governing equation and units yourself. Enter the same data into the calculator, compare the result, then review the assumptions and limitations. For exam preparation, use the tools to verify practice problems rather than replacing the derivation. Professional design still requires the applicable code, load combinations, safety factors and engineering judgement.

FE and university exam note

Exam rules determine which physical calculators, reference handbooks and software are permitted. This page is a learning and checking resource; verify the current rules of your specific exam before test day.
