Agymnast with mass m1 = 43 kg is on a balance beam that sits on (but is not attached to) two supports. the beam has a mass m2 = 115 kg and length l = 5 m. each support is 1/3 of the way from each end. initially the gymnast stands at the left end of the beam.
1)what is the force the left support exerts on the beam?
2)what is the force the right support exerts on the beam?
3)how much extra mass could the gymnast hold before the beam begins to tip?
now the gymnast (not holding any additional mass) walks directly above the right support.

4)what is the force the left support exerts on the beam?
5)what is the force the right support exerts on the beam?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
