Introduction to Engineering

Spring 2017

Here’s a real challenge for you.....

You are given a

7

” x

7

” piece of

aluminum foil. Your challenge is to use this foil to make

a “boat” which can hold 100 pennies without sinking.

You may

work on this outside of class

but you will need to procure your

own aluminum

foil and pennies. You may also choose to bring your own materials to our next class

but, if you opt not to,

I will provide th

e

materials

(but yo

u should know that I will only give

you one piece of foil)

for you to demonstrate your solution.

H

owever, before just trying this,

you

should

think about the problem, perform some

calculations and even make a

prot

otype (perhaps

out of paper) to

make sure that on

“game day” you can make the real one

(if you don’t bring yours in)

.

You may initially think this is impossible because neither of the materials floats

, but

remember.....steel doesn’t float and there are steel ships sail

ing all over the world.

Here are a few things which may help you:



Think about why steel ships

float



What is the principle which is used?



How do you know how low a ship will sit in the water

?



Can you calculate how low your boat will sit in the water?

Hopefully you think so

because I am requiring it

What I would like to see is the process you went through in order to develop your

solution. This may include ideas, sketches, calculations, prototypes, and anything else

you have used in your design and de

velopment effort. Remember that we all think

differently so use what works best for you.
