<u>Deflation</u> is the process by which wind removes surface materials.
<h3><u>Explanation</u>;</h3>
Erosion refers to a process in which soil, rock, and other surface material are removed from their location and transported to another by natural agents such as water and wind.
<em><u>The main mechanism of wind erosion is deflation. Deflation involves erosion by wind of loose material from flat areas of dry uncemented sediments such as those in deserts, dry lake beds, flood plains etc. The removed particles are then transported to another region where they may form sand dunes on a beach or in a desert.</u></em>
Rod is 450mm and disk has a radius of 75mm So there is a pin holding the assembly upwards which is when Θ=0 and at the pin there is a torsional spring with constant of k=20N m/rad. One end of the rod is attached to the pin and the other is attached to the disk.
