Settling Conflicts
A conflict is a result of a…

Moral Issue
 if it can only be resolved by appealing to moral
principle.

Conceptual Issue
 if the morality of an action is agreed upon, but
there is no written definition of the company rule
or law

Application Issue
 if it is unclear if a act violates a written rule or law.

Factual Issue
 if more data is needed.

Background Information (Handout)
City Ordinance: No sounds above
90 decibels after 10:00 PM.
You have a problem with your
neighbor making loud noises.
Identify the type of issue for these
conflicts.


Case 1: You are angry about some loud
music coming from your neighbor’s party.
You both measured the loudness at 1:30AM.
You measured 100db and she measured 85
db. This leads to a heated discussion. What
type of issue lead to this conflict?
Case 2: You and your neighbor Sam both
complain to the apartment manager about a
car alarms sounding too often in the
apartment complex. Every Saturday
afternoon you take a nap around noon after
working out in the gym. One Saturday Sam’s
car alarm wakes you up. You are upset by
this and go next door to discuss it with Sam.


Case 3: Your neighbor plays music on
Halloween night at 11:30pm with a loudness
of 70 db. You are worried about that the
children in the neighborhood will be
“emotionally scarred” by the strange music
and call the police.
Case 4: You live near a company that cleans
glass with ultrasound starting at midnight
when the workers are at home sleeping. The
ultrasound is 110db but is not audible. You
are bothered because it shakes the picture
frames in your home and go to the company
to complain.

Case 5: You awake at 2:30 AM to find
that your neighbor has started a heavy
metal band. The music is 115db at
your doorstep. You go ask the band if
they can play in the daytime instead
but the band refuses. What type of
issue lead to this conflict?

Engineering Exercise
You are asked to build a storage tank
for 22 cubic meters of gasoline.
You want to use the least amount of
metal to keep your construction costs
low.
Suppose that you use 1-centimeter
thick steel sheets to create storage
tanks.
Engineering Exercise (con’t)
If you had a tank in the shape of a
cube, then how long would each side
be?
What would be the inner surface area
of the tank?
How much metal would you need?
Engineering Exercise (con’t)
If you had a tank in the shape of a
sphere, then what would its radius be?
What would be the inner surface area
of the tank?
How much metal would you need?
Engineering Exercise
If you had a tank in the shape of a
cylinder, then what would its radius be?
What would be the inner surface area of
the tank?
How much metal would you need?
Aha!
We will need to make some assumptions.

How do we know that h=2r
is the best?
1. We can use trial-and-error.
2. We can prove it using calculus.
Archimedes’ Principle
The buoyant force acting on a floating
body is equal to the weight of the
media (air or water) that is displaced.
Example Problem

the water line?
rwood = 0.600 g/cm3
rwater = 1.00 g/cm3
40cm
