Procedure:
For this part
of the experiment we need to use the equation power=tω
so we will first find the total torque by the system then
we will find ω.

Finding torque total:
By using equation
manipulation we get
t=RM(g-Rα)
where α is rotational acceleration and g=9.8m/s^2
α=a/R
a=2(y-y0)/t^2
plugging the numbers
a=0.106m/s^2
α=4.82
t=0.00842N
t=RM(g-Rα)
where α is rotational acceleration and g=9.8m/s^2
α=a/R
a=2(y-y0)/t^2
plugging the numbers
a=0.106m/s^2
α=4.82
t=0.00842N
finding ω:
ω=RPM(2pi/60)
where pi=3.14156
plugging in we get
ω=0.413
where pi=3.14156
plugging in we get
ω=0.413
now for
watts:
power=tω
power= 0.003477
or 3.477mW
Now that we have the output power we can find what is going in and compare them.
power= 0.003477
or 3.477mW
Now that we have the output power we can find what is going in and compare them.
