A crate of mass 95 kg crate lies on a plank inclined at 23,20. At this angle the crate is just about to move down the incline. Refer to the diagram below. 23,2 3.1 Define the term frictional force. (2) 3.2 Sketch a free body diagram showing the force(s) acting on the crate at its current (3) position. 3.3 CALCULATE: 3.3.1 The magnitude of the static frictional force (3) 3..3.2 The coefficient of static friction between the plank and the block. (5) 3.4 The plank is now tilted at an angle of 20.03. State whether the static friction force will be LESS THAN; EQUAL TO; OR GREATER THAN Question 3.3.1 above. (1) [14]
