How much is it? On average, a breathalyzer will cost around $150 to $300 to install in your vehicle or sometimes more if your car starts without a key. Newer technology, such as the built-in car breathalyzer that scans your finger, costs an estimated $200 to install.
Strength Of Materials. Strength of Materials, also referred to as Mechanics of Materials, looks at the behavior of materials when forces are applied to them. These forces include different types of stresses upon and within the material in all different directions, and the strain that is experienced in the material due to those forces.
Flexural strength. The flexural strength is stress at failure in bending. It is equal or slightly larger than the failure stress in tension. Flexural strength, also known as modulus of rupture, or bend strength, or transverse rupture strength is a material property, defined as the stress in a material just before it yields in a flexure test.
