Concept review: axial loading

Purpose

This optional learning activity will help you review the concepts of axial loading. (It does not assess problem-solving ability, however.)

• Module 05 Objective 1 State Saint-Venant's principle.
• Module 05 Objective 2 List the conditions necessary for the force-deformation relationship to be valid.
• Module 05 Objective 3 Apply the sign conventions for elongation, internal axial force, normal stress, and normal strain.
• Module 05 Objective 4 Analyze a statically determinate system of axially-loaded structural members.
• Module 05 Objective 5 Analyze a statically indeterminate system of axially loaded structural members.
• Module 05 Objective 6 Define and distinguish between thermal strain and mechanical strain.
• Module 05 Objective 7 Report changes in temperature and coefficients of thermal expansion in appropriate SI and US customary units.
• Module 05 Objective 8 Analyze a statically determinate system of axially loaded structural members undergoing changes in temperature.
• Module 05 Objective 9 Analyze a statically indeterminate system of axially loaded structural members undergoing changes in temperature.

These Module Objectives support the following course learning outcome(s):

• define each of the following mechanical properties: modulus of elasticity, ductility, yield strength, ultimate strength, and coefficient of thermal expansion; and describe how each property characterizes the material response of a linear elastic, homogeneous, isotropic material or structure.
• calculate and illustrate the normal and shear stress components, normal and shear strains, and deformation of standard idealized elements such as shafts, beams, columns, and thin-wall pressure vessels due to axial, torsional, and flexural loads, pressurization, and/or changes in temperature.  

Task

For each question, select the best answer. Discussion and collaboration is encouraged!
Chegg and similar "homework help" websites are prohibited, due to numerous errors that misinform and confuse students.
The correct answers will be made available after you submit your first attempt. If you would like clarification, ask Jenny.
Learn the concepts so that you are able to answer all the questions correctly. Attempt this learning activity as many times as you would like.

Grading Criteria

This optional learning activity is not graded.

You will receive the most benefit from this learning activity if you discuss the questions and answers with classmates.
