ME 257 - Strength of Materials for Nonmechanical Engineers3 lecture hours 2 lab hours 4 credits
Course Description
This course is for nonmechanical engineering students. The course provides non-MEs with a background in the area of strength of materials including what is required in the selection of materials to meet actual application requirements. Subjects include the stress-strain relationship, elasticity, as well as axial, torsional and shear stresses and deformations. Interrelated laboratory experiments reinforce the concepts presented in the lecture/analysis sessions. (prereq: ME 255 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• take a structural member, simply loaded, and find principle (max.) normal stresses, shear stresses and their angular locations within the member
• calculate beam deflections and deformation angles under various lateral loadings using the principle superposition
• be familiar with various tests used in industry to determine material properties, as well as being able to utilize the test outputs
