Question
A laboratory on the concept of static equilibrium uses an
apparatus called a force table. The force table consists of a
round, level platform marked in degree increments about its
circumference. In the center of the table sits a massless ring, to
which three strings are tied. Each string is strung over a
m,
separate pulley clamped to the edge of the platform, and then
m2
tied to a freely-hanging mass, so that each string is under
m3
tension and the ring is suspended parallel to the table surface.
A mass of m1 = 0.161 kg is located at 0,
= 26.5°, and a
second mass of m2 = 0.223 kg is located at 02 = 287°.
Calculate the mass m3 and the angular position 03 (in degrees)
that will balance the system and hold the ring stationary over the center of the platform.
