Transcribed Image Text:On the graph to the
right, draw a coordinate
axis. Draw in the two
force vectors. Show
by adding the vectors
graphically that the
net force on the central
ring is zero. Verify this
algebraically by showing
that the sum of the.
components is also zero.
L
+) = N
the position.
Now, notice that you can slide the ring back and forth along the r axis, placing it at any
distance, and the ring will stay in place. This means that every point along the r axis is an
equilibrium point. Explain why this is the case.
The forces Cancel it does not matter
FYEN
Now we're going to change the axes. Remove the two pulleys, and place them at angles
of 90° and 270°, respectively. Keeping the z axis along = 0, we've now placed the forces
along the y axis. Repeat the earlier analysis with the new forces.
