If we assume that the string is inextensible, then . We further assume that the string and pulley are massless, and that the pulley is frictionless. Then the tension appearing the the first and third equations is the same.

Physics Problems to Challenge Understanding, ... (a) and (b) are wrong because the rope has relatively small mass, so the tension forces at its ends are nearly the same size (F =ma where m is essentially zero). Certainly any small difference in tension between the two ends is nowhere near great enough to account for...

Hi I have just started a introductory physics course to get refreshed after 6yrs away from any schooling and I am stuck with how to find out tensions in ropes suspended from a horizontal beam with a 100N weight attached by 2 rope 3m and 4m in length 5m apart.

Indeed, if dA = Ldx, then dF = (γL)dx, as if γL were a tension in dynes. This is the usual definition of surface tension, though even school physics makes it clear that it is really a free energy per unit area. When a surface is extended, it cools, and heat must flow in to maintain isothermal conditions.
