The two-time string or p-brane action can be gauge fixed to produce various one-time string or p-brane actions that are dual to each other under gauge transformations. We discuss the particular gauges that correspond to tensionless strings and p-branes in flat (d-1)+1 spacetime, rigid ...

Homework Statement A cylinder of mass m is suspended through 2 strings wrapped around it at its ends, connected to the ceiling. Both strings have equal tension, and the cylinder rolls without slipping. r is the distance between the CM of the cylinder and each end. I is the moment of iner...

All it says is that the upward-pulling tension has to be equal to the two downward forces (gravity and the other tension). But what about the sum of the torques? If the object is in equilibrium, you can pick any point on the object to calculate the torque. I'm going to pick point...
Analysis of tennis string tension I have a decent background in physics, but something that has always confused me is how to think about how the tension of the string in a tennis racquet affects how the ball leaves the strings. For example, the traditional lore in tennis is that tauter...

Frequently Asked Questions What is IOQP? For the 2021-2022 session of INPhO, only one qualifier examination was conducted known as the Indian Olympiad Qualifier for Physics (IOQP). This examination had two parts: Part 1: National Standard Examination for Physics (NSEP) and Part 2: Indian Nati...
BlockTensionVelocity Replies: 27 Forum:Mechanics Block of mass M attached to rope of mass m We have the string's mass constraint m(x) = m(x/L). The block is accelerated right by force T(x=0) = Ma, where a = F / m + M. But at the point where the force is applied (i.e....
