Agricultural engineers study and evaluate applications of engineering technology to agricultural problems. They design farm machinery, structures, and equipment, and they plan and supervise manufacturing, construction. and installation Ceramic engineers study, design, and evaluate chemical processes and manufacturing plants which produce bricks, glass. and pottery. Chemical engineers study, design, and evaluate the commercial processes for producing the chemical or physical transformation of substances, such as petroleum derivatives, metals, food, and synthetic materials, and they plan and supervise the manufacturing plant and its construction, operation, and maintenance. Civil engineers study, design, and evaluate large structures such as bridges, dams, roads. Computer engineers analyze and design physical systems.
Engineering mechanics are experts on how solids and fluids react under forces.
They are specialists employed on sophisticated or highly complex design, research, or development problems. Geological engineers apply a knowledge of geological sciences and engineering fundamentals to such engineering endeavors as the exploration, development, and utilization of mineral and petroleum resources or to the locations and construction of engineering projects. Industrial engineers study and evaluate the organization of production processes and commercial and administrative procedures. Materials engineers study and evaluate characteristics of materials and they endeavor to develop new material for general or specific purposes or to find new uses for present materials. Mechanical engineers study, design, and evaluate mechanically functioning equipment and they plan and supervise the development, manufacture , construction , installation , operation , and maintenance of such equipment .
