(a)block A weigh 60N. the coefficient of static friction between the block and the surface on which it rests is 0.25. the weight W is 12N and the system is at equilibrium. find the friction force exerted on block A. (b)find the maximum weight W for which the system will remain in equilibrium.

    Something is missing here. Is the block on a ramp?

  • physics - ,

    no its on a flat surface with the static friction of .25. and W is hanging off the string at a 45 degree angle vertically.

  • physics - ,

    What is W attached to? I totally don't understand the picture.

  • physics - ,

    the string off of A
