A bag of cement whose weight is Fg hangs in equilibrium from three wires as shown in Figure P5.33. Two of the wires make angles θ1 and θ2 with the horizontal. Assuming the system is in equilibrium, show that the tension in the left-hand wire is SNIPP
A horse is hitched to a wagon. Since the wagon pulls back on the horse just as hard as the horse pulls on the wagon, why doesn’t the wagon remain in equilibrium, no matter how hard the horse pulls?
Is it possible to explain why the total tension in a rope is not zero if the two ends of a rope in equilibrium are pushed with forces of equal magnitude and in opposite directions?
