Concept review: average normal stress and average shear stress (direct shear stress)

Purpose

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

• Module 01 Objective 1 Define normal stress and shear stress.
• Module 01 Objective 2 Use appropriate symbols to represent normal stress and shear stress.
• Module 01 Objective 3 Report average normal stress and average shear stress values with appropriate SI and US customary units.
• Module 01 Objective 4 Distinguish between tensile and compressive normal stress.
• Module 01 Objective 5 Calculate and illustrate average normal stress or average shear stress on a given plane within a structural element.

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

• calculate and illustrate the normal and shear stresses at a given point on a given plane within a structural element.

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.
