Factor affecting surface tension?
The main factor is the strength of cohesion between molecules. For instance, water molecules have a slightly negative and a slightly positive end which makes them stick together like magnets. A molecule with more extreme positive and negative charges would have a stronger surface tension.
Thension crack is generated by the difference in shear movement along the failure surface or slip plane. It formed in the upper slope face before the major failure surface appeared. So, the total shear resistance and thus the safety factor will reduce after this tension crack developement. However, this tension crack will stop developing when it reaches a critical depth. And, a new tension crack will develope behind that previous crack.
Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example, in floating of some objects on the surface of water, even though they are denser than water Some Examples of Surface Tension Let us see some more interesting effects of the surface tension in our daily life: 1) Dew drops: Have you noticed the drops of water on the leaves in…
One is the liquid's surface tension. A drop of water will be quite spherical because is has strong surface tension, meaning the edges of the droplet are drawn into the centre. Another factor could be the speed with which the drop falls, as the air particles will have to be pushed apart quicker, making the droplet more streamlines, therefore less spherical.
