 In this Project, we are going to calculate the drag force over a bicycle using MATLAB programming and draw a plot Drag Force vs Velocity. A drag force is the resistance force caused by the motion of a body through a fluid, such as water or air. A drag force acts opposite to the direction of the oncoming flow velocity.…

Air cushion vehicles(ACV) are used to break ice in cold places, where ice is formed on the surface of lakes, rivers and on the roads too. Depending on the ice thickness , an ACV can readily break ice in flexure by making a depression and send cracks throgh the ice. Once a crack is made , the path of least resistance …
