Modulus of elasticity: The ratio of the stress applied to a body to the strain those results in the body in response to it. The modulus of elasticity of a material is a measure of its stiffness and for most materials remains constant over a range of stress. . Material | Elastic Modulus | | MPa | psi | Steel | 200‚000 | 30‚000‚000 | Poisson ratio It is the negative ratio of transverse to axial strain. In fact‚ when a sample object is stretched (or squeezed)‚ to an extension (or contraction)

Summer heat and vehicle emissions are just a few of the contributing factors that increase air pollution levels. However‚ healthy trees planted effectively along roads‚ buildings and in parking lots can decrease overall air pollution levels for city residents.Trees can remove both gaseous air pollutants and particulate matter. Gaseous air pollution enters a tree

of Air Pollution Air pollution depending upon which source you use is broken down in a couple of ways. No matter how you look at it though‚ air pollution is still air pollution and it is both harmful to humans and the environment. One source breaks air pollution down into two categories or seven primary and two secondary pollutant types (Wright & Boorse‚ 2008‚ p. 487). The primary pollutants can more easily be broken down into four types of pollution which are based upon the reason or cause. These
