Description

pic

Factors influencing the proportioning of machine elements: stresses, deformations, and failure criteria as applied to shafts, springs, belts, bearings, gears.

Who Takes It

Design of Elements is a required course for mechanical engineering students. This course is an introduction to the basic principles of modern engineering. It provides the students with fundamental skills of engineering, and the ability to apply the theories of science to practice.

What It's About

The course focuses on the fundamentals and principles of basic mechanical elements, failure theories and design criteria, and structures of basic mechanical systems. The goal of the course is to learn how to design simple mechanical elements and systems.

It includes:

  • Understanding the principle of each element.
  • Analyzing elements mechanically by applying the theories from statics, dynamics, mechanics of materials, and fluid mechanics with deterministic or statistic approaches.
  • Learning how to design basic elements and simple systems.
  • Designing elements and systems by means of CAD.

Lectures

  • Getting ready for design of elements
  • Failure theories
  • Variable loading and fatigue criteria
  • Introduction to shafts
  • Transmission elements
  • Rolling element bearings
  • Fluid-film bearings
  • Connecting elements
  • Other elements and review

Labs

One lab each week on CAD of components and assembles
