Unformatted text preview: 2 1 in. A concentrated load of 350lbf is applied at the beam end, perpendicular to the length of the beam. If the uncertainty in the length is 5 . 1 ± in., in the diameter is 08 . ± in., and in the force is 5 ± lbf, what is the uncertainty in the calculated maximum bending stress? Problem 4 (10 points) (Prob. 3.38 of the textbook) The forcedeflection data for a spring are tabulated below. Determine a least squares fit. Deflection, in. Force, lbf 0.10 9 0.20 19 0.30 22 0.40 40 0.50 52 0.60 59 Problem 5 (10 points) The following data points are expected to follow a functional form of b ax y = . Obtain the values of a and b by converting the functional form to a linear relationship between log(x) and log(y). x 1.21 1.35 2.40 2.75 4.50 5.10 7.1 8.1 y 1.20 1.82 5.00 8.80 19.5 32.5 55.0 80.0...
