A horizontal 4.0 m long plastic bar at one end is attached to a wall by a frictionless hinge and atthe other end is held down by a wire that is at 60 ° to the horizontal as shown. It needs to beheld down because the bar is of negligible mass (so you can take its mass to be zero) and at the middle of the bar is a 1.6 kg balloon that is 4.2 m3 (those are the total mass and volume foreverything: a rubber envelope and the helium in it). What are the magnitudes of the horizontal and vertical components of the force on the bar due to the hinge? Hint: First apply Newtons second law to the balloon to determine the tension of the stringbetween the balloon and the bar
