Pulley Weight problem

  1. Oct 25, 2006 #1
    Two weights W1 and W2 are suspended from the ends of a light string passing over a smooth fixed pulley. If the pulley is pulled up at an acceleration 'g', then what will be the tension in the string? Solution : [te
    x]\frac{4w_{1}w_{2}}{w_{1} + w_{2)}[/tex]

    I have calculated that the tension in the spring assuming that the pulley is not accelerating. I know to find the acceleration also(if the pulley is not acclerating). How do I proceed?

    thanks for your time.

    Hint: both the masses will be accelerated upwards at g. So what will be the additional tension in the string.
