m=50.0 kg and unknown mass ma locate on opposite ends of a uniform seesaw of mass m=30.0 kg which is L=12.0 m in length as shown in the figure. The seesaw is placed on a fulcrum which is located a=5.00 m from the left end. When mo, ma and the fulcrum are all placed as stated, the see-saw is stationary (under equilibrium condition). Assume the force of the fulcrum exerts on the seesaw is N. B 7m A a = 5m a) (10%] How many total forces onto the seesaw? b) (10%] Where is your rotation axis? c) [20%] Write the necessary equation(s) when the seesaw without translational motion d) [40%] Write the necessary equation when the seesaw without rotation e) (10%) Find the mass MA. f)[10%) Find the force of the fulcrum exerts on the board N.
