QUESTION 6 Which of the following is/are NOT true about strain gauges? Please select all that apply. a. Strain gauges are designed to change resistance due to stretching b. Strain gauges are configured in Wheatstone bridge circuits to measure large changes in resistance c. Strain gauges directly measure stress on the surface of a structure d. Strain gauges directly measure the kinematic properties on the serface of a structure QUESTION 7 Which of the following is/are true for a curve-fit using a least-squares regression analysis? Please select all that apply. a. We choose our polynomial coefficients such that the SSE (sum of the squared error) is equal to zero. b. We assume the independent variable (i.e., the experimental input) shows no random error. c. We assume the measurement error scales with the measured value. d. We can arbitrarily fit any polynomial we like when analyzing our data. e. We assume the error in the measured value is distributed normally.
