Best ResponseYou've already chosen the best response.0is my diagram right?

Best ResponseYou've already chosen the best response.0sag in rope due to mass of rope ?

Best ResponseYou've already chosen the best response.0then u wud take 'mg = 2T cos(theta)' is it im not sure how the entire mass of rope gets manifested at center ?

Best ResponseYou've already chosen the best response.0that's the tension at the end of the rope , but i'm looking for the tension in the middle

Best ResponseYou've already chosen the best response.0oh tension can be different thru out the rope in this system ?

Best ResponseYou've already chosen the best response.0since the rope has mass... things may not be ideal hmm

Best ResponseYou've already chosen the best response.0yes the rope is uniform density , and has a total mass of m

Best ResponseYou've already chosen the best response.0yes i think we can make these assumptions

Best ResponseYou've already chosen the best response.0yeah in the middle of the symmetric rope

Best ResponseYou've already chosen the best response.0It would depend on the length between tethers and the length of the rope.

Best ResponseYou've already chosen the best response.0So if we're leaving this general, it's just based on the angle, which doesn't really matter to us though.

Best ResponseYou've already chosen the best response.0Unless they're telling us the length of the rope and the length of the distance it's stretched across, then we're screwed.

Best ResponseYou've already chosen the best response.0the tensions should be a function of (m,θ,g)

Best ResponseYou've already chosen the best response.0So the rope's not moving right? That means the forces up and forces down should be equal, right? So... mg=2Tcos(theta) Solve for T, problem solved.

Best ResponseYou've already chosen the best response.0That's assuming all the mass is in the center?

Best ResponseYou've already chosen the best response.0Since it has a uniform density, center of mass is there, so it's safe assumption.
