ENGR& 225 Mechanics of Materials (5 credits)
Distribution Area Fulfilled General Transfer Elective
Formerly ENGR 240 - CCN
Prerequisite ENGR& 214 with a minimum grade of 1.5, and PHYS& 221 with a minimum grade of 1.5
Course Description
An introduction to the principles of Mechanics of Materials. Students will analyze the force, moment, stress, strain, and deformation in solid materials under tension, compression, shear, torsion, and bending. Students will learn about different mechanical tests and how to analyze and interpret their stress-strain diagram.
Course Content
A. Axial and shear stress and strain analysis
B. Mechanical properties and stress-strain curve graph analysis
C. Thermal stress and stress concentrations
D. Torsional stress and angle of twist
E. Statically Indeterminate Axially- and Torque-loaded Members
F. Shear and bending moment diagrams
G. Bending stress and transverse stress
H. Combined Loadings
I. Allowable Stress and Beam design
J. Stress-strain transformations and Mohr’s Circle
Student Outcomes
-
Examine axial and shear stress and strain in axially-loaded members and the resulting deformation
-
Read and interpret stress-strain curve graphs from different mechanical tests for the purpose of calculating a material’s mechanical properties
-
Analyze torsional shear stress and angle of twist in circular members
-
Evaluate bending and transverse stress in straight members
-
Calculate stress-strain transformations for stresses, strains, and principal stresses and strains using equations and Mohr’s circle
-
Evaluate state of stress caused by combined loadings
-
Collaborate effectively with peers to solve mechanics of materials-related engineering problems
Degree Outcomes
Critical, Creative, and Reflective Thinking: Graduates will evaluate, analyze, synthesize, and generate ideas; construct informed, meaningful, and justifiable conclusions; and process feelings, beliefs, biases, strengths, and weaknesses as they relate to their thinking, decisions, and creations.
