Bar Restrained With Spring Uniform Heat Applied Calculator

Bar Restrained With Spring and Uniform Heat Applied Calculator and Equations

Bar Restrained One End and Gap on Other Formula and Calculator

Bar Restrained Against One End and Gap on Other Stress and Force Calculator and Equations A bar rigidly mounted with uniform heat applied will expand and exert force and axial stress onto itself and adjoining surfaces.

Restrained Beam Thermal Expansion Force Axial Stress Calculator

When a structural element is subjected to a change in temperature, it will either expand or contract depending on whether the temperature change is an increases or decrease

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.

Extension Spring Hook Design Calculator and Equations

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

Diameter Change in Compression Spring Calculator

When a helical compression spring is compressed, an increase in the outside diameter occurs because the angularity of the coils changes so that it is nearly at a right angle to the axis.

Short Rectangular Membrane Stress and Deflection Calculator

The stress at various locations on short rectangular membranes are given by following equations and calculator

Long Rectangular Membrane Design Calculator and Equations

Long Rectangular Membrane Stress and Deflection Design Calculator and Equations

Circular Membrane Stress and Deflection Calculator and Equations

A membrane may be defined as a plate that is so thin that it may ne considered to have no bending rigidity. The only stresses present are in the plane of the surface and are uniform throughout the thickness of the membrane.

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.

Stress at Threaded Tube Connection Design Calculator

Stress at Threaded Connections Between Two Tubes Design and Calculator

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.

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.

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

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

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)

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

Estimating UAV Drone Propeller Thrust Equations and Calculator
