Tire Pressure vs Load Calculator and Equation

If the rated tire pressure is unknown or a more precise tire pressure vs load is required the following equations and procedure can be followed.

Diameter Changes in Compression Springs Formulae and Calculator

Most compression springs are open coil, helical springs which offer resistance to loads acting to reduce the length of the spring. The longitudinal deflection of the springs produce shearing stresses in the spring wire.

Composite Sandwich Stiffness Equation and Calculator

The analysis procedures described on this webpage apply to composite sandwich structures having isotropic facings and either orthotropic or isotropic cores.

Structural Composite Sandwich Design and Analysis in Aerospace Applications

Structural sandwich is a layered composite, formed by bonding two thin facings to a thick core. It is a type of stressed-skin construction in which the facings resist nearly all of the applied edgewise (in-plane) loads and flat wise bending moments. The thin spaced facings provide nearly all of the bending rigidity to the construction.
