A 50 cm x 30 cm x 20 cm block weighing 150 N should be moved at a constant speed of 0.8 m/s up an oblique plan with a coefficient of friction f= 0.27. a) Determine the force F required in the horizontal direction. Hint: friction force= f. normal force. b) Determine the percentage of force reduction if there is a 0.4 mm thick oil film between the block and the oblique plane. The oil has a dynamic viscosity of 0.012 Pa . s. 50 cm 150 N 20 30 cm V=0.8 m/s A 50 cm x 30 cm x 20 cm block weighing 150 N should be moved at a constant speed of 0.8 m/s up an oblique plan with a coefficient of friction f= 0.27. a) Determine the force F required in the horizontal direction.
