A block is resting on a wooden plank. There is a hinge on one end of the plank which allows the other end to be lifted to create an angle, θ, with respect to the horizontal as shown in the figure. The coefficient of static friction between the block and the plank is μs.  Please use the interactive area below to draw the Free Body Diagram for the block. Use Fs to denote the force of static friction.   The angle θ is slowly increased. Write an expression for the angle at which the block begins to move in terms of μs.

Question

A block is resting on a wooden plank. There is a hinge on one end of the plank which allows the other end to be lifted to create an angle, θ, with respect to the horizontal as shown in the figure. The coefficient of static friction between the block and the plank is μs.

 Please use the interactive area below to draw the Free Body Diagram for the block. Use Fs to denote the force of static friction. 

 The angle θ is slowly increased. Write an expression for the angle at which the block begins to move in terms of μs

If a student measures that the block begins to move at an angle of θ = 25°, what is the numerical value of the coefficient of static friction, μs
