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.
Fatigue strength is also known as endurance strength or fatigue limit. Fatigue strength is used to describe the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure, or the highest stress that a material can withstand for a given number of cycles without breaking.
