Lab Report 6 Help

FOR LAB REPORT 6 Part 1 "PREPARATION"

Question 1:

T net = I*alpha

omega = omega_0+alpha*t

omega_0 is the Initial angular velocity

Equation (2) shows that, when plotting the angular velocity vs time, the graph is
linear with its slope = angular acceleration

Question 2:

I = (m*r*(g-r*alpha))/(abs(alpha_fr)+alpha)

Question 3:
C = 3, D= 5, E= 6, H= 1 , F=7, B= 4, A=2, G=8

Question 4:
D=1, F=4, C=2, A=6, B=3, E=5

Question 5:
I_disk = .5*M*R^2
Fill in answers in order - > greater than, greater than, very small compared to, small compared to, quadratically

Question 6:
L = I*omega
Iw = Iprime*omegaprime

Question 7:
I' = I+I_disk

Question 8:
D= 4, B= 3, A= 1, C= 2

Question 3:
Correct Statement: The slope of the graph has to be negative

Just a note

For Questions 3&4, I just noticed that they change the numbers around so don't follow what I posted because it will be different for everyone. The questions are pretty easy if you look at the lab manual.

this is due before or after lab?

I'm not really sure, this new format for the labs is kind of confusing, I don't even know what we're supposed to use as a report sheet but from what I understood - this part is due before lab and the execution part is due after lab. I think they're trying to start doing this in place of the lab quiz. I don't have lab until thursdays though so if anyone has it before then let me know the process

after this lab it is due before the lab. I am quite sure for this one you can do it after the lab

what are the units for omega and alpha?

anyone understand ques 6 for the execution part?

anyone know the syntax for ques 8 for the execution part?

I = (m*r*g)/(abs(alpha_fr)*alpha)

I=constant x r

DelatI=Deltar/r*I

i appreciate it

anyone got ques 8??

anyone understand ques 10??

Thanks

The units for omega are rad/s
The units for alpha are rad/s^2

Can someone please put up their times and velocities for the first graph (Frictional Acceleration) my trend might be incorrect. I hope someone can please put this up soon so I can see if we should redo it or not. Thanks.

anyone know how to find L, i used L=Iw but its not working for 15?

what is first I in #6

and 8 plzzzzzz

what is SI unit for w in #12 and 13
thanx

omega's (w) SI unit is rad/s

hello guys, i need help with this too

first I in #6 only the first one , i got the other three and #8 if possible

thanx

sqrt((DeltaM/M)^2+((2*DeltaR)/R)^2)*I_disk

sqrt(DeltaI^2+DeltaI_disk^2)

I = (m*r*g)/(abs(alpha_fr)+alpha) you add alpha not multiply..

I=constant x r

DelatI=Deltar/r*I

did anyone get question 14...how to fine DeltaL?

For the first I, the answer is (m*r*g)/(abs(alpha_fr)+alpha)
Someone had posted the denominator as being alpha_fr*alpha but that is not the case, they are supposed to be added not multiplied
