A man weighing 500 newtons sits in swing suspended with two ropes if each rope makes an angle of 30 degree with the vertical, what is the tension in each rope?

Answer 1

sketch the diagram. First, assume only one rope.
vertical load on the hinge: mg
tension= mg/cos30
so tension on each of two ropes is half that. weight mg = 500
tensioneachrope=250/cos30
