this coefficient depends on the surfaces of both the wood and inclined plane
here is a procedure how to determine it:
1) position the wooden block on the horizontal plane
2)start elevating slowly one end of the plane, thus increasing the angle from 0 upwards
3)at the moment the block start sliding -- measure the angle
4)for this angle calculate normal reaction that the plane exert on the block(this depends on the block's mass and the angle) and magnitude of that component of the gravity force of the block along the plane (the 'driving' force)
5)the coefficient is the ratio of the reaction over gravity component forces( the mass of the block will obviously cancel)

You have two surfaces. The coefficient of static friction cannot be determined without knowing the material the inclined plane is made of. The surface quality should also be given for each.
For clean, dry wood, the coefficient can range from .25 to .5 times the angle.

Physics is not the process of looking up equations. Physics is the process of understanding the relationships between quantities. If you do not understand the relationships, then all the formulas in the world will be useless to you. There is no "formula for finding the coefficient of friction." Formulas are relationships between quantities. To have a relationship, you need more than one. To what other quantities do you want to relate coefficient of friction?

What is MOC of inclined plane?
substance CO-EFFICIENT OF FRICTION
wood on wood 0.25-0.50
steel on steel 0.58
glass on glass 0.9-1.0
(There are two forms of friction, kinetic and static. If you try to slide two objects past each other, a small amount of force will result in no motion. The force of friction is greater than the applied force. This is static friction. If you apply a little more force, the object "breaks free" and slides, although you still need to apply force to keep the object sliding. This is kinetic friction. You do not need to apply quite as much force to keep the object sliding as you needed to originally break free of static friction.)

the coefficient of friction between any two surface depends on the nature of the two surface OK! you have to find it out by experiment. in any problem on physics where you have to calculate the friction, the coefficient has to given in the question itself

2.33 times the angle of the plane.
