MATSE 259 Exam 1 PSU Questions and Answers | Latest Version | 2024/2025 | Graded A+ How does strain relate to deformation in materials? Strain is the measure of deformation representing the change in length relative to the original length. What is yield strength? Yield strength is the stress at which a material begins to deform plastically. Why is Young's modulus important in materials science? Young's modulus measures a material’s stiffness, or resistance to elastic d...

Heat Treating correct answers Changing the steels microstructure, which alters its mechanical properties such as hardness, strength, ductility, and toughness. Phases: correct answers 1. Ferrite- A soft, ductile BCC phases 2. Austenite- A FCC that can dissolve more carbon Transformation correct answers When steel is heated, it can transform from ferrite -> austenite. Upon cooling it can transform back to ferrite, form carbides or form intermediate phases. Carbon Solubility correct an...

MMET 206 Exam #1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ What is the primary difference between ferrous and non-ferrous metals? Ferrous metals contain iron, while non-ferrous metals do not. What property of a material measures its ability to conduct heat? Thermal conductivity. Why are polymers typically more flexible than metals? Polymers have a molecular structure that allows them to bend without breaking due to long- chain molecules and weaker intermole...

MMET 207 Final Review Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is the primary purpose of using a micrometer in a mechanical lab? A micrometer is used to measure small dimensions with high precision, typically within a range of millimeters or fractions of an inch. What are the key benefits of using Computer-Aided Design (CAD) software in engineering? CAD software enhances design accuracy, facilitates modifications, and allows for detailed 3D modeling and si...

MMET 207 Lab Final Exam Questions and Answers | Latest Version | 2024/2025 | Graded A+ What is the main purpose of metallography in materials testing? Metallography helps analyze the microstructure of metals to determine material properties, such as grain size, phase distribution, and defects. Why is it essential to use mounting and polishing in sample preparation? Mounting and polishing ensure a smooth, even surface that allows for clear microscopic examination of the sample's ...

MMET 207 Exam 1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ What is the primary purpose of metallography in material science? Metallography is used to analyze the microstructure of metals, which helps in understanding their properties and performance under various conditions. What effect does strain rate have on the ductility of metals? Increasing the strain rate generally decreases the ductility of metals, leading to more brittle behavior during deformation. I...
