MET 214 – Machine Elements

Course Description

The theories and methods developed in statics, dynamics, and strength of materials are applied to the selection of basic machine components. The course will develop the fundamental principles required for the selection of the individual elements of which a machine is composed.

Course Objectives

  1. Recognize examples of mechanical systems in which the application of the principles discussed in this course is necessary to complete their design.
  2. Present design calculations in a professional, neat, and orderly manner that can be understood and evaluated by others knowledgeable in the field of machine design.
  3. Specify suitable types and sizes of belts and sheaves (chains and sprockets) to transmit a given level of power at specified speeds for the input and output sheaves (sprockets).
  4. Recognize and describe the main features of different gears.
  5. Define train value as it pertains to the overall speed ratio between the input and output shafts of a gear box.
  6. Compute the forces exerted on gear teeth as they rotate and transmit power.
  7. Use appropriate stress analyses to determine relationships among applied forces, the geometry of gear teeth, and other specified factors , in order to make decisions about those variables.
  8. Compute the forces exerted on shafts by gears, belt sheaves, and chain sprockets.
  9. Specify the time required to accelerate a system or to bring it to a stop with the application of a given torque using brakes /clutches.
  10. Integrate the mechanical concepts necessary to complete a preliminary design of a conveyor system.
