1. A viscous oil flows down a wide plate with a uniform depth of 8 mm and an average velocity of 50 mm/s. The plate is on a 3° hill and the specific gravity of the oil is 0.85. Determine the average shear stress between the oil and the plate.
2. Water flows in a 5-m-wide channel with a speed of 2 m/s and a depth of 1 m. The channel bottom slopes at a rate of 1 m per 1000 m. Determine the Manning coefficient for this channel.
The graph shows how the force component F cos along the displacement varies with the magnitude s of the displacement. Find the work done by theforce. (Hint: Recall how the area of a triangle is related tothe triangle's base and height.)
