    Why Isn't the String's Mass Included in Block B's Tension?

    Homework Statement In the diagram above, a massless string connects two blocks- of masses m1(left) and m2(right), respectively- on a flat frictionless tabletop. A force F pulls on Block A, as shown. If the string connecting the blocks were not massless, but instead had a mass of m, figure...

    Relationship between normal force and sum of the force in elevator problem

    Thank you for responding me! But when dealing with pulley, the directions of the ropes are supposed to be opposite no? Or it could be making them the same charges..im just confused..

    Relationship between normal force and sum of the force in elevator problem

    Homework Statement A 80.8 kg man inside a 40.0 kg dumb-waiter pulls down on the rope. At that moment the scale on which he is standing reads 200N. Determine the elevator's acceleration (basically the man is inside the elevator pulling a rope that goes around the pulley, which makes the...
