Answer the following problems in detail.
problem 1) Describe the developments in the shape of cars starting from car from Camille Jenatzy in 1899 to the shapes of modern cars. describe the features in terms of fuel efficiency, speed, luxuries etc.
problem 2) describe the motion of the vehicle resisted by Aerodynamic drag, rolling resistance and climbing resistance.
problem 3) describe completely about detail optimization and shape optimization performed as strategies for aerodynamic development of passenger cars.
problem 4) describe the effects of natural wind, wind forces due to steady side winds on aerodynamic stability of a vehicle.
problem 5) Describe the concept of hatch back, fast back and square back for shape optimization of cars.
problem 6) With the help of neat and well labelled diagram, describe the role of a wind tunnel. describe the different construction elements and their working.
problem 7) With the help of neat and well labelled diagram, describe the phenomena of laminar and turbulent boundary layer, their separation and friction drag on a body in two-dimensional flow.
