Help. I cannot figure this out! A chandelier hangs h = 0.52 m down from two chains of equal length. The chains are separated from one another by a length L = 0.75 m at the ceiling. The chandelier has a mass of m = 19 kg. Write an expression for FT,y, the magnitude of the y-component of the tension in one chain, in terms of the given information and variables available in the palette.

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
