. The stress, S, on a pipe varies jointly with the internal pressure, P, and the internal diameter, D, of the pipe and varies inversely with the thickness, T, of the pipe. The stress on a pipe is 100 pounds per square inch when the internal pressure is 25 pounds per square inch, the diameter is 5 inches, and the thickness is 0.75 inches. a) Write the variation equation describing the problem. b) Find the constant of variation or proportionality. c) Find the stress in pounds per square inch when the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inches.

Question
Transcribed Image Text:. The stress, S, on a pipe varies jointly with the internal pressure, P,
and the internal diameter, D, of the pipe and varies inversely with
the thickness, T, of the pipe. The stress on a pipe is 100 pounds per
square inch when the internal pressure is 25 pounds per square inch,
the diameter is 5 inches, and the thickness is 0.75 inches.
a) Write the variation equation describing the problem.
b) Find the constant of variation or proportionality.
c) Find the stress in pounds per square inch when the internal pressure
is 40 pounds per square inch, the diameter is 8 inches and the
thickness is 0.50 inches.
