Intense research is underway to develop adiabatic engines that require no cooling of the engine block. Such engines are based on ceramic materials because of the ability of such materials to withstand high temperatures. Write an essay on the current status of adiabatic engine development. Also determine the highest possible efficiencies with these engines, and compare them to the highest possible efficiencies of current engines.
Regarding amorphous plastics, explain why they tend to have higher tensile strength when deformed compared to when not. please include an illustration
Explain and critically evaluate injection molding and provide an ICT diagram of the process
