MAE 2381 FINAL EXAM QUESTIONS
WITH VERIFIED ANSWERS 2025/2026
precision - ANSWERamount of dispersion expected with repeated measurements
Accuracy - ANSWERrefers to how close a measured value is to an accepted value
Bias - ANSWERoffset value, tendency to over or under estimate a population
parameter
linearity - ANSWERthe closeness of a calibration curve to a straight line
Calibration - ANSWERact of applying a known input to a system to observe the
output of the system, establishes connection between input and outputs
hysteresis - ANSWERdifferences in the measured value between upscale and
downscale sequential tests
What causes hysteresis? - ANSWERwhen the output of a measurement system is
dependent on the previous value given by the system
time constant - ANSWERsystem property defining the time required for a first order
system to respond to 63.2% of a step input
What does a smaller time constant mean? - ANSWERindicates a shorter time
between the instant that an input is applied and when the system reaches a steady
output
rise time - ANSWERtime required for a system to respond to a value that is 90% of
the step input
static sensitivity - ANSWERrate of change of the output signal relative to a change in
a static input signal. The slope of the static calibration curve at a point
damping ratio - ANSWERa measure of a system's ability to absorb or dissipate
energy
undamped natural frequency (second order) - ANSWERwhen the damping ratio is 0
Wn=W
What happens when a system is undamped? - ANSWERsystem will oscillate
continuously, no friction is present
What happens when the damping ratio is between 0 and 1? - ANSWERsystem is
underdamped, will oscillate but will stabilize to the steady output value
