EGR 130 - Statics and Strength of Materials for Engineering Technology (5 CR.)

Course Description

Presents principles and applications of free-body diagrams of force systems in equilibrium. Analyzes frames and trusses. Presents principles and applications to problems in friction, centroids, and moments of inertia. Includes properties of materials, stress, strain, elasticity, design of connections, shear and bending in statically determinate beams, and axially loaded columns. Lecture 4 hours. Laboratory 2 hours. Total 6 hours per week.

General Course Purpose

The purpose is to introduce the student to the fundamental principles which characterize forces on bodies at rest and the properties, characteristics, and design of structural members of mechanical systems. Student will be able to solve fundamental mechanics problems and determine stresses and deformations of structures caused by systems of forces. Student will learn mechanical properties and their application in determining the structural members’ size and shape.
