How to determine the static frictional force?

[shizzledizzle]

Homework Statement

We have to do a lab on friction in which there was a pulley with a mass attached to it which is held by another mass on the table and an inclined plane with a mass on it. The question is "Based on your work above, show why μs = m/M". I don't understand how to do this. Also "what is the static frictional force on the wooden block equal to?"

Homework Equations

The mass on the table holding the mass dangling off the pulley is 'M' and the mass dangling off the pulley is 'm'

The Attempt at a Solution

Maybe the mass is giving off a force to the mass on the table? But how would I explain this? And the second question would it be that Fs = μN?

The question isn't clear! Could you draw a diagram?
The usual approach for this type of question is to draw the forces on each mass and then write that the sum of the forces = 0 for each one.
