Discuss the importance of the streamlined shape of a fish. |
| Answer» Solution :A fish experiences viscous DRAG force while moving through water. The boy of a fish is tapered at the head and at the TAIL, and is compressed at the sides. This is a type of streamlined shape. For this reason, a fish experiences less viscous drag force while swimming through water and the water flowing by the fish follows streamlines. So they are able to control their DIRECTION of motion very EASILY. For the same reason, the shape of aeroplanes, fast moving trains or racing CARS, are made streamlined. | |
