25
CATEGORY:
Homework
DESCRIPTION:
For each of the following, use sketches, clear calculations, and explanations. Complete all
work in your notebook.
1.
Using your balloon, estimate the mass of air contained in the balloon. Show all
calculations. Assume the pressure in the room is 11.4 lb/in2. Assume the pressure
in the balloon is twice the pressure in the room.
2. Determine the time it takes your balloon to move from hood to hood in the
classroom (avoiding your fellow classmates). What does this tell you about the
thrust capabilities of the balloon (in words)? What properties affect this thrust?
3. Assuming you can push down with a force equal to your body weight, design a
system using hydraulic principles to lift Dr. Albertson’s Subaru Impreza. Assume
her car, fully loaded with dog food and dogs, weighs 3500 lbs. Draw the system,
show all sample calculations, and provide a short explanation of your reasoning.
DELIVERABLE:
Clear and neat answers to the problems above using the given, find, equations, solution
method discussed in class. Box all answers and ensure you are clear on units. Show
ALL your interim work. Just an answer will not get you full points on the assignment.
