Increasing your water heater temperature by just 10ÂºF from 130ÂºF to 140ÂºF may increase heat loss resulting in a larger electric bill from $30 to $75 dollars annually. Setting the temperature to 140ÂºF can also increase demand losses resulting in an annual expense of up to $500 dollars.
Material that is very strong and tough but shows very little elongation as it absorbs energy Kevlar Material that is the best choice for the support beams of a building
1 A stiff material has a high Young's modulus and changes its shape only slightly under elastic loads (e.g. diamond). 2  A flexible material has a low Young's modulus and changes its shape considerably (e.g. rubbers). A flexible material has a low Young's modulus and changes its shape considerably (e.g. rubbers). 2  A stiff material requires high loads to elastically deform it-not to be confused with a strong material, which requires high loads to permanently deform (or break) it.
