A block rests on a smooth inclined plane that makes an angle of 30° with the horizontal. The block is acted upon by the following forces:

Question Parts

( a )
Given that the coefficient of static friction between the block and the plane is 0.40, calculate the magnitude of the normal reaction exerted by the plane on the block.
( b )
Using the result from part (a) and the given coefficient of friction, determine the magnitude of the tension in the rope required to keep the block at rest.
( c )
Calculate the magnitude of the frictional force acting on the block.
( d )
If the horizontal push is increased from 150 N to 200 N while all other conditions remain the same, state qualitatively whether the block will move up the plane, down the plane, or remain at rest. Justify your answer with a brief calculation.
