Helical Torsion Spring Reaction End Design Calculator and Equations

Frequently, the limiting stress value in helical torsion springs is the stress value in the ends.

Jan 31, 2024

Extension Spring Hook Design Calculator and Equations

The hooks at the ends of extension springs are subjected to both tension (bending) and torsional stresses.

Press Fit Bushings into Lug Stresses Calculator and Equations

Pressure between a lug and bushing assembly having negative clearance can be determined from consideration of the radial displacements. After assembly, the increase in inner radius of the ring (lug) plus the decrease in outer radius of the bushing equals the difference between the radii of the bushing and ring before assembly.

Hole Sizes Cold Form Tapping Metric Threads

On materials that can be die cast, cold form tapping can be done in cored holes provided the correct core pin size is used.

Jan 4, 2024

Theoretical Tapping Hole Size Cold Form Threads

Conventional tap drill sizes should not be used for cold form tapping because the metal is displaced to form the thread.

Jan 3, 2024

Tap Drill Size as Percentage of Engagement Calculator

The size of the tap drill hole for any desired percentage of full thread depth can be calculated by the formulas below.

Shock Mach Diamond Formulas and Calculator

Shock diamonds (also known as Mach diamonds or thrust diamonds) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system

Dec 27, 2023

Mach Wave Calculator

a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow

Dec 27, 2023

Oblique Shock Calculator and Equations

An oblique shock wave is a shock wave that, unlike a normal shock, is inclined with respect to the incident upstream flow direction

NACA Airfoil Plotter and Equations

The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA)

Dec 21, 2023

de Laval Nozzle Exhaust Gas Velocity Equations and Calculator

A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, making a carefully balanced, asymmetric hourglass shape
