When a 100-N bag of nails hangs motionless from a single vertical strand of rope, how many newtons of tension are exerted in the strand? How about if the bag is supported by four vertical strands?
please explain what this question is asking, and what the answer is and why. i really want to try and understand physics. thanks =)When a 100-N bag of nails hangs motionless from a single vertical strand of rope, how many newtons....?
Since the bag is motionless, the system is in equilibrium. This means that the downward pull of the weight of the bag is exactly matched by the tension in the rope, which then has to be 100 N.
If the four strands are identical, and all are vertical then the load is equally distributed. Each has a 25 N tension.
