5. (12)A balance beam device comprised of a 200 cm long beam of unobtainium (no mass) ]
\]and a fulcrum located in the middle of the beam is balanced straight and level. At the right side of the beam system a mass of 30 kg is attached and at the other end of the beam system a mass of 25 kg is attached.
Find:
a) the torques acting on the system
b) the net torque and direction of rotation
c) Yippie the wonder dog, well beyond the prime of life, sees the problem of the unbalanced system with failing eyes. Yippie leaps up to the top of the fulcrum and after a less than stellar landing at the fulcrum point begins limping about on the left side of the fulcrum. The years have not been kind; our beloved Yippie has porked out to 25 kg (table orts you know). Help out, where must Yippie sit to bring the system into balance?
