R1-R2 > 0 or R1-R2<0 DISC CW BEAM opposite to CW .
TWO IDEAL OPPOSITE FORCES (-F,-F )
WE CAN USE SUPERPOSITION RULE
AND PUT forces ( -F,F) to place where is rope or
to center M2--m--M1
m - beam
M2 shoes
M1 Disk
if M1=M2 and all is perfect We will not see any radial forces
but only rotation ( disk CW - Beam CCW )
PROBLEM IS IF ROPE IS NOT IN IDEAL CENTRAL POINT
M1>M2
ABOVE TOY IS ABLE PUSH EARTH WITHOUT REACTIONS !!!
ONE FORCE (-F) is PUSHING mass M1-m-M2 body ideal in center
point
NEXT (-F ) force is trying push Earth ( Space ship if rope we will conect to celing in spaceship )
.................^
.................^ -F
.................^
M1-------m ---X---C-----------M2
......................I
......................I
......................I -F
C - central point for mass M1-m--M2
X- rope
PROBLEM IS TIME ABOVE STATICA !!!
HOW MUCH TIME NEED FORCES TO FIND BALANCE !!!
NOT EXIST NOW all need time !!
NOT EXIST PERFECT MODEL IN REAL LIVE BUT BEFORE
WE MAKE TEST WE NEED UNDERSTAND IDEA
(-F, -F ) it is not constant !
