Block B in the figure weighs 752 N. The coefficient of static friction between block and table is 0.32; angle θ is 33°; assume that the cord between B and the knot is horizontal. Find the maximum weight of block A for which the system will be stationary.

|dw:1441020009343:dw| Set up the equations: equilibrium at the knot: \(mg = T ~tan(\theta)\) At the point of movement, \(\mu~Mg=T\) Solve for m.

oh, thanks but i meant how did you solve for that, and how did you get 0.32?

The coefficient of static friction is the ratio of the maximum friction force and the normal reaction between two objects when neither of the objects is moving. (ref. wiki plus corrections)

It's given in the question: "The coefficient of static friction between block and table is 0.32; "
