Angular Acceleration
Name: Carlos Hernandez
Partners: Dahlia Tran.
Date: October 31 and Novemebr 2 of the year 2016
Theory: We want to apply some known torque to a system and measure/understand its relationship to angular acceleration. Different trials will be done changing stuff to the system to understand the virtues that compose angular acceleration.
Lab Constraints: In this Lab we will be doing different trials. to the right of the picture above, one may appreciate that there are three disks that will be subject to rotational motion using a air valve that makes the disks move the disks have a string attached a that goes over and out the table like so ^ and a mass is attached to the string hanging off the table. And logger pro to measure the angular velocity over time.
Procedure: Now that we have all that we need we will turn on the air valve and let the cylinders move. For the first experiment we used a hanging mass of only .025 Kg with the torque pulley on the top being small and the Disk that will rotate will be only the top. (At this point both the bottom and the top are steel ). We do this for 6 trials with the mass changing, as well as witch disk moves and of what material (steel or aluminium) and the torque pulley being either small or large,(the large doubling the small in diameter). Below will be a picture of the six experiments and there corresponding constraints.
Logger Pro Procedure: In the photo above one may see that there are values for angular acceleration down , up and average.
