Text Book, Title, Author and Year:
Machine Elements in Mechanical Design-4Th Ed. By Robert L. Mott, Prentice Hall
Introduction to the Course:
a. Catalog Description (2010-2011 Academic Catalog):
The methods developed in statics, dynamics, and strength of materials are applied to the selection of
basic machine components. The fundamenetal principles required for the selection of individual
elements that compose a machine are developed. Selected course topics are included as computer
exercises.
b. Prerequisites or co-requisites:
Prerequisite: MET 21100 and MET 21300 or consent of instructor
c. Required course.
Specific Goals to the Course:
a) General Education Objectives:
Upon completion of this course the student will be able to:
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

4) Demonstrate how to calculate mass moment of inertia for useful shapes encountered in machine
elements including cylinders.
Chapter 3 Review of Strength of Material
5) Introduce combined stresses
6) Work examples that serve as introduction to force systems associated with gear systems of various
types including spur gears and/or helical gears.
Chapter 7 Flexible Power Transmission Elements, belt drives and chain drives
7) Work example problems involving flexible power systems (may want to analyze linear slide
system/Ball screw combination being driven by a chain drive)
