1
State the central method of Engineering Model Assumptions, Sensitivity & Reporting and list the conditions that must be checked.
Faculty solution: Use documenting geometry, density, units, uncertainty, and limitations. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
A pumping model assumes constant density. Name one situation where this may fail.
Faculty solution: Temperature or concentration gradients can make density vary with depth.
3
What belongs in an engineering integration memorandum?
Faculty solution: Diagram, variables and units, assumptions, derivation, computation, sensitivity or error analysis, and a defensible conclusion.
4
A learner makes an error by dropping density, pressure, probability, or physical units. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is dropping density, pressure, probability, or physical units. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Engineering Model Assumptions, Sensitivity & Reporting in mechanical work, fluids, structures, reliability, and probabilistic decision-making. Define variables and identify the quantity an integral, differential equation, sequence, or series would measure.
Faculty solution: A defensible response defines variables and units, states assumptions, builds the correct mathematical object, and interprets its value in mechanical work, fluids, structures, reliability, and probabilistic decision-making.
6
Describe two independent ways to verify a result from Engineering Model Assumptions, Sensitivity & Reporting.
Faculty solution: Use an exact structural check such as differentiation, substitution, partial sums, or theorem hypotheses; then compare with numerical, graphical, dimensional, or limiting evidence.
