Sample Practice Problems

Preview the types of problems and questions covered in this worksheet

Below are sample questions representative of the exercises included on this worksheet and related 12.80 Elasticity, Stress, Strain, and Material Limits skill assessments:

Problem 1Difficulty: Mastery

Which capstone statement best connects modulus, yield strength, and toughness for material selection?

AHigh modulus automatically means highest toughness

BYield strength is irrelevant if stress is measured in pascals

CToughness is the same property as density

DHigh modulus means small elastic strain, but yield strength and toughness still limit safe use

Solution & Explanation:Modulus controls elastic strain for a given stress. Safe design also depends on when permanent deformation begins and how much energy the material can absorb before fracture.

Problem 2Difficulty: Mastery

A rotating flywheel rim experiences tensile stress during operation. Which material choice is most defensible for safe design?

AThe most brittle material as long as it is very stiff

BAny material because rotation produces no stress

CA material with high tensile strength, adequate toughness, and a safety margin below operating stress

DA material chosen only by color and density

Solution & Explanation:For a highly stressed rotating part, strength alone is not enough; toughness and a safety margin help reduce the risk of sudden failure.

Problem 3Difficulty: Mastery

Use the unloading graph. The specimen is unloaded from point B at stress 360 MPa and total strain 0.0070. The elastic unloading slope is 180 GPa. What is the permanent strain?

A0.0020

B0.0050

C0.0070

D0.0090

Solution & Explanation:The recoverable elastic strain is σ/E = 360 MPa/180 GPa = 0.0020. Permanent strain = 0.0070 - 0.0020 = 0.0050.
