I'm not following the drawing..
@amistre64 do you?
it looks familiar, you are prolly trying to find the Rs to put the system in equilibrium.
think of a complicated seesaw
Yeah i trying to make it equilibrium
I need to find the r value
|dw:1348490479611:dw|
if i were to take a guess; r1 = -20 r2/.8 = 16(1) -20(.8) r2 = 16(.8) -20(.64) = 0 .... been too long
theres is some interplay between distance and force ....
For this we should find that the upward forces are equal to downward forces
This question is about moment M = Fd
http://demonstrations.wolfram.com/EquilibriumOfASuspendedMobile/ this looks pretty cool
yeah, its just to early for me to focus thru this :/ ill think on it and come backl later to see if theres any progress on it
Ahh ok Thnx for ypur help this too complicated for me too I'll be looking for an answer from u
This question is about rotation the clockwise and anti clockwise but bcauz of these forces it won't rotate and I have to find the R1 and R2 value
@Miyuru you'll have better luck getting help if you actually ask a question (don't forget to state it fully and clearly)
the net torque or couple on the system is zero.
equilibrium means the condition of balancd state or rest condition.in this case net force and torque on the system is zero.
|dw:1348513729666:dw|an idea i have, right or wrong, as to take an arbitrary fulcrum. And the left should equate to the right
-16(.9) + R1(.7) = -16(.1) + R2(.9) -14.4 + R1(.7) = -1.6 + R2(.9) R1(.7) = 12.8 + R2(.9) R1 = (12.8 + R2(.9)).7
