If this is an introductory activity, then it is really not important that students understand the details of specific heat capacity at this point! It is just important that students understand that different materials heat up and cool down at different rates; this has important implications for life on Earth. A material's specific heat capacity is the amount of heat (or energy) required to increase the temperature of one kilogram of the material by 1Â°C.
Mechanical Drawing Symbols. Mechanical systems drawing is a type of technical drawing that shows information about heating, ventilating, and air conditioning. It is a powerful tool that helps analyze complex systems. These drawings are often a set of detailed drawings used for construction projects; it is a requirement for all HVAC work.
What Mechanical Engineers Do. Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers design, develop, build, and test mechanical and thermal devices, including tools, engines, and machines.34,750. The median annual wage for mechanical engineers was $80,580 in May 2012. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $52,030, and the top 10 percent earned more than $121,530.
