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
â¢ Elongation is important in components which absorb energy be deforming plastically (e.g. crash barriers, car bumpers). â¢ High elongation to failure is important for plastic hinges (e.g. video cassette boxes). â¢ Elongation is important in manufacturing - it measures how much bending and shaping a material can withstand without breaking.
