Textbook Question
Chapter 13, Problem 1RQ
An environmental engineer has obtained a bacteria culture from a municipal water sample and has allowed the bacteria to grow.
- a. Show the resulting data and trendline, with equation and R2 value, on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear.
- b. Assume the value of m in the resulting model is the growth constant. Use the trendline determined to find the value and units of the growth constant for these bacteria.

The beam AB is attached to the wall in the xz plane by a
fixed support at A. A force of
F = (−129î + 69.0ĵ + 3591) N is applied to the end of
the beam at B. The weight of the beam can be modeled with
a uniform distributed load of intensity w = 85.0 N/m acting in
the negative z direction along its entire length. Find the
support reactions at A.

A bent pipe is attached to a wall with brackets as shown. A
force of F = 180 lb is applied to the end of the tube with
direction indicated by the dimensions in the figure.
Determine the support reactions at the brackets B, C, and
D. Model these brackets as journal bearings (only force
reactions perpendicular to the axis of the tube) and neglect
couple moment reactions. Assume the distance between the
supports at B and C and the tube bends nearby are
negligible such that the support at C is directly above the
support at D and the dimension g gives the distance between
supports B and C. Enter your answers in Cartesian
components.
