Calculators for forces, pressure, torque, materials, gears, beams, and unit conversions.
Compute force using Newton's Second Law (F=ma), gravitational force, spring force (Hooke's Law), and centripetal force.
Calculate mechanical pressure (P=F/A), hydrostatic pressure in fluids, and convert between pressure units.
Calculate rotational force / torque (τ = F × r) and convert between torque, mechanical power, and RPM.
Calculate gear speed ratios, output RPM, mechanical torque multiplication, and gear train reductions.
Convert between linear surface speed (m/s, ft/min) and rotational speed (RPM) for wheels, pulleys, and spindles.
Calculate total weight and volume of metal plates, round bars, tubes, and sheets (Steel, Aluminum, Copper, Brass).
Calculate surface area and volume for 2D plane shapes (circles, triangles) and 3D solids (spheres, cylinders, cones).
Calculate maximum bending moment, shear forces, and deflection for simply supported and cantilever structural beams.
Compute electric, hydraulic, and mechanical motor power requirements in kilowatts (kW) and horsepower (HP).
Specialized engineering unit converter for pressure, stress (MPa/psi), dynamic/kinematic viscosity, energy, and flow rates.
