Design/build lab practicum – bennett m. and luke s.

The fan with lots of angles

The time ticks tic tock because the ball rolls to the finish

This is a lab practicum for that BFPM objective. This practicum involves a frictionless track and fan cart, a fixed fan, some spring scales, and a bit of card board (or folded paper).

Question: The pressure exerted through the Fan around the Cart (fan 1) around the Cart is .25N (or anything you measure) far away of 21cm apart, the pressure exerted through the stationary fan around the cart is .2N (or anything you measure). Making no additional measurements, setup the position of fan 1 so the cart is stationary far away of 21cm (or whatever you decide) in the stationary fan.

Extra Question: The fan cart has scores of 350g. Whenever a 500g mass is positioned onto it, set the position of fan 1 again in order that it rests at 21cm (just like before) when both fans are switched on. [Note: the solution with this you will not vary from the final question. If you wish to turn it into a bit more difficult you are able to ask what will change backward and forward problems. The reply is when released from far enough it’ll oscillate slower before becoming stationary at 21cm.]

Extra Question 2: Repeat the very first problem however with a small incline towards the track.

SETUP:

To setup, firmly attach the card board towards the front from the fan cart.

Then setup the stationary fan around the finish from the track, facing the card board side from the fan cart.

Next make use of a spring scale to determine the pressure from the fan around the cart around the cart at HIGH. Next, switch on the stationary fan and employ the spring scale to determine the pressure from the stationary fan around the fan cart. Choose a distance backward and forward fans that ensures the the stationary fan is applying more pressure around the cart compared to fan around the card is applying around the cart.

Ready!

Faculty Consultant: Kelly O’Shea

Please write an account from the project you’re proposing. Why would you like to take this on, and just what would you aspire to learn?

We’ll designing and building lab equipment (specifically for lab practicums). I’ve helped kelly build experiments before and also have found it very enjoyable. Kelly may also share our designs using the bigger physics teaching community.

What’s your suggested outcome? How would you have the ability to demonstrate effective completing this Project?
