This video demonstrates a basic tensile test. Tensile testing, or tension testing, is a type of mechanical test used to determine how a material responds to a stretching force. This test helps to evaluate the mechanical properties of a materials. In a tensile test a a load is applied to a specimen. The load is gradually increased until failure

This video shows a summary of the basic vacuum resin infusion process for the manufacture of a carbon fibre and epoxy composite.

Calculate the theoretical density of Iron in g/cm^3. Given that the Atomic Weight is 55.847 g/mol. The lattice parameter, a = 286.6 pm (picometers), and Avogadro’s constant Na = 6.02x10^23 atoms/mol.
