10 ICSE, Revision A needle placed on the water can be floating due to the surface tension of the water. The film formed due to surface tension tends to hold the surface in place and due to this, the entire liquid is pulled upwards, when the edges are pulled upwards. However, when the stream is marked by chaotic changes then it is called turbulent flow. It is defined as the ratio of the highest load applied to the wire to its original cross-sectional area. There are two forms of longitudinal stress.-. A rectangular wireframe of size 2 cm x 2 cm, is dipped in a soap solution and taken out.
