1. The space between two parallel plates 12 mm apart is filled with crude oil. A force of 5 N is required to drag the upper plate at a constant velocity 0.95 m/s. The lower plate is stationary. The area of the upper plate is 900 cm². Determine the dynamic viscosity and kinematic viscosity of the oil, if the specific gravity of oil is 0.96. Q1 The anchor shackle supports a cable force of 3.0 kN. If the pin has a diameter of 6 mm, determine the average shear stress in the pin. 6 mm 3.0 kN
