Click the Introduction tab. A. Select the small crate from the drop down option.
B. Change the values of the ramp angle to zero so that the surface is horizontal.
C. Adjust the object position to be at 8.0.
D. Now, slowly increase the ramp angle until you reach an angle when the small crate is about to move. Angle = 22 degree.
E. Keeping the same angle, what minimum applied force do you need to move the crate up the inclined plane? Drag the small crate along the direction of the inclined plane and observe the changing values of the applied force. Applied force UZX 15 N 276.
F. Draw the free body diagram.
G. Switch small crate with File cabinet and repeat steps b through f. compare the angle and the applied forces you found for small crate. Which quantity didn't change its value? if so why?
H. Now, change the object to mysterious object and try to find the angle of the ramp in which the mysteries object about to move. Angle = 17.6 degree.
I. What is the mass of the mysterious object?
J. What will be the minimum applied force needed to for the mysterious object to move along the horizontal plane?

The inside surface of a cylindrical-shaped cave of inner diameter 1.0 m is continuously covered with a very thin layer of water. the cave is very long and it is open on both ends. the water on the cave surface is at a constant temperature of 15.5 °c. the cave is constantly exposed to wind such that 15.5 °c air flows through the cave at 4.5 m/s. the kinematic viscosity of the air is 14.66 x 10-6 m2/s and the molecular diffusion coefficient of water vapor in the air is 0.239 x 10-4 m2/s. because the cave diameter is so large, the flow of wind down the length of the cave, in the x direction, can be treated like it is external flow and the cave surface can be approximated as flat where appropriate. calculate the x value, in a) the transition to turbulent flow occurs at rex meters, where the air flow transitions from laminar to turbulent along the inside surface of the cave b) calculate the x value, in meters, where the bulk steady state concentration of water vapor in the air flowing in the cave is 10% of the saturation concentration. assume the air at the surface of the water layer is 100% saturated with water vapor. assume the wind entering the cave contained no moisture before it entered the cave. take into account the transition from laminar to turbulent flow when solving part b
