21. TAKING A CLOSER LOOK AT THE ROLE OF AN INDUSTRIAL ENGINEER Copyright © 2014 Discovery Education. All rights reserved. Discovery Education Inc. is a subsidiary of Discovery Communications, LLC. Industrial engineers find ways to eliminate wastefulness in production processes. They devise efficient ways to use workers, machines, materials, information, and energy to make a product or provide a service. Depending on their tasks, industrial engineers work both in offices and in the settings they are trying to improve. For example, when observing problems, they may watch workers assembling parts in a factory or staff carrying out their tasks in a hospital. When solving problems, they may be in an office at a computer looking at data that they or others have collected.

37. HEAT TRANSFER Heat is a type of energy. It is measured by temperature. All substances contain heat, even a cold treat. If there is a difference in temperature in a system, heat flows from the substance with the higher temperature to the substance with the lower temperature. Insulation is used to slow unwanted temperature changes. It can be used protect against heat or to prevent heat loss. Copyright © 2014 Discovery Education. All rights reserved. Discovery Education Inc. is a subsidiary of Discovery Communications, LLC. Temperature regulation applies an understanding of the principles of heat transfer, which is relevant in almost all engineering disciplines. Electrical and computer engineers design electronics so that they do not overheat. Mechanical engineers make sure that working engines do not overheat. Packaging engineers design containers and systems to be able to ship items at specific temperatures. Temperature regulation is an important part of engineering. Civil engineers specify the most suitable insulating materials for the climates where their structures reside.
