Question 1074562: The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. The stress is 100 pounds per square inch when the diameter is 5​ inches, the thickness is 0.75​ inch, and the internal pressure is 25 pounds per square inch.
Find the stress when the internal pressure is 50 pounds per square inch if the diameter is 7 inches and the thickness is 0.50 inch.

k, a constant
y, stress in a pipe
x, internal pressure
d, internal diameter
t, thickness


highlight_green%28y=kxd%2Ft%29



kxd%2Ft=y

k=yt%2F%28xd%29


GIVEN VALUES
y=100
d=5
t=0.75
x=25


FIND VALUE FOR k
k=%28100%2A0.75%29%2825%2A5%29

k=75%2F%2825%2A5%29

k=3%2F5

FINISHED FORMULA
highlight_green%28y=%283%2F5%29%28xd%2Ft%29%29


You can finish the question part.
