material selection properties-what are the requirement for the most suitable structural material? Correct Answer-the structural material that combine stiffness and elasticity are considered the most suitable material. material selection properties-elasticity? Correct Answer-The ability of a material to bounce back after being disturbed - the ability of the body to deform under stress, bend, stretch and compress when the external forces are applied and return to its original shapes when the ...

The Law of Conservation of Mass indicates that the amount of raw material entering a process must equal the amount of material leaving the process. correct answers True Most proteins found in food denature at a pH of 7. . correct answers False, 7 in neutral The glass transition in bread is important because the loss of moisture at the crust layer causes loss of crispness and initiation of rubbery texture in the crust. correct answers False, gain of crispiness Whether knife, abrasion, or...

GE 2000 Exam 2 MTU Questions and Answers brittle, ductile, and elastic strain - CORRECT ANSWER-faulting - broken block flow - stretched back elastic - reversible, not permeant effect on material elastic limit - max stress before permanent effect ductile - irreversible permanent change in shape or volume rupture/fracture - material breaks the factors that affect the strain a rock experiences - CORRECT ANSWER-rock composition confining stress (d...

MMET 401: Exam 1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ How do mechanical properties influence the behavior of materials under stress? Mechanical properties, such as tensile strength and elasticity, determine how materials deform and fail under applied forces. What role does the stress-strain curve play in understanding material behavior? The stress-strain curve illustrates how a material responds to stress, providing insights into its elasticity, yield point...

MMET 207 Exam III Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is one key characteristic that distinguishes ductile materials from brittle materials? Ductile materials can undergo significant plastic deformation before fracture, while brittle materials fracture with little to no deformation. What is a notable advantage of using aluminum in structural applications? Aluminum is lightweight yet strong, making it ideal for applications where reducing weight is cru...

tunnel failure ~ - squeezing (ductile) - spalling (brittle - with structure (complex) riks: - rockburst -overstress in sedimentary rocks road header ~ tunneling method - weak rock excavation drill and blast ~ tunnel method - explosives and detonators shielded TBM ~ erects liner within shield single shield TBM ~ tunnelling beneath water table, weak ground, flowing soil earth pressure balance TBM ~ - keeps a mixture of earth material and water under pressure at the face to prevent...

Fracture is a type of material failure. Of the following which is another type of material failure? - Answer-Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? - Answer-Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: - Answer-NDT involves indirect tests related to some other quality or characteristic of material. What are...

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...
