Textbook Question
Chapter 3.4, Problem 18E
The vertical displacement v of a cracked slurry infiltrated fiber concrete member at maximum shear stress is given by v = a + bw, where w is the crack width, and a and b are estimated from data to be a = 2.5 ± 0.1 mm and b = 0.05 ± 0.01. Assume that w = 1.2 ± 0.1 mm.
- a. Estimate v, and find the uncertainty in the estimate.
- b. Of the uncertainties in w, a, and b, only one has a non-negligible effect on the uncertainty in v. Which one is it?

(a) Determine the equation of the best-fit
line that relates the normal stress and the
shear resistance of the metal specimen.
Evaluate the goodness of the fit of the said
equation.
A 2.2-m-long steel rod must not stretch more than 1.2 mm when it is subjected to a 9.0-kN tension force. It is given that E=
200 GPa.
Determine the corresponding normal stress in the rod.
The corresponding normal stress in the rod is
MPa.
A simple spring is used to measure force. The spring is
considered to be linear, so that F = kx, where F is the force in
Newtons, k is the spring constant in newtons per centimeter,
and x is the displacement in cm. If x = 12.5 + 1.25 cm and k =
700 + 18 N/cm, calculate the best estimate of the uncertainty
of the measured force in relative terms (i.e., in terms of % of
the measured force).

The ratio R = Vo/V₁ is called the coefficient of restitution. Following are measurements of the coefficient of restitution for 40 randomly selected baseballs.
