The block of M = 5 kg , modeled as a particle, rests on the inclined surface
Question:
The block of Mkg modeled as a particle, rests on the inclined surface that makes an angle of heta with the horizontal ground. The static friction coefficient between the block and the surface is mu s A force of P is horizontally applied on the block. Take gms for convenience.
Q Draw a freebody diagram FBD of the block.
Q Write down Cartesian vector expressions for all forces shown on your FBD with respect to the specified coordinate system shown.
Q Find the range of P needed to keep the block to rest on the surface without sliding down or pushing up
Q Find the critical value of P such that the static friction force between the block and the surface is zero.
Hint: The block could slide down for a significantly heavy block or be push up if P is too big
Q Write down the scalar component form of the equilibrium equations in the x and y directions.
