The app calculates the refractive index of transparent materials based on wavelength. It also computes light transmission angles, reflection and transmission coefficients, critical angle, and Brewster’s angle.
Calculate Maidenhead locations and HF dimensions. Input frequency and select elements to determine reflector, driven element, director, and spacing sizes in feet, inches, and meters. Convert area measurements between square inches and square feet.
Fan Law Calculator allows users to input rpm, cfm, static pressure, and horsepower. Modifying one value recalculates the others. Ductulator helps size HVAC ducts by inputting shape, dimensions, air temperature, elevation, and roughness.
Calculate CFM requirements for air actuators with real-time results. Size compressors and air receiver tanks based on system needs. Analyze pressure drops and optimize pneumatic systems with engineering-grade calculations.
Calculates 2D plane stress solutions. Determines max and min stress, max shear stress, average stress, and principal stress plane angle. Displays normal stress at arbitrary angles. Allows users to verify diagram accuracy and perform stress analysis.
