(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?
Answered by andrew
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.

What is W attached to? I totally don't understand the picture.
Answered by andrew
the string off of A
