1. A 10kg dumbbell resting on a table is partly supported by a spring that pulls upward with a force of 50 N. a. Draw and label the forces on the free-body diagram. b. Calculate the weight in newtons and label it on the free body diagram. 50 N 10 kg c. If the dumbbell is not moving then the net force on it must be zero. Use this fact to calculate the support forces. You may assume they are both equal. d. What force would the spring have to exert to make the support forces exactly zero? 1.
