a) The magnitude and direction of the force required to balance the stick, if it is applied at the 30 cm mark

b) The magnitude of the normal force of the fulcrum on the stick

A student places a mass of 25 grams near the end of the meter stick (at the 5 cm mark) and moves the balance point (the fulcrum) from the former center of gravity of the meter stick at 50 cm to the 42 cm meter mark. There is no additional weight on the opposite side of the meter stick, but it is now in balance. What conclusions and generalizations can you make from the following data collected by a student...
