hi everyone...
I am new comer and new for phsyics..
I have a problem for the following question.
/|
/ |
/ mass
/
/__________
A B
From point A to B is a simple bridge mad from uniform 6 m long platorm. A rope of negligible mass is attached to other end point A. this rope passess over a smaill frictionless pulley and supports a 110 kg mass on its other end. The angle between the rope and the bridge is 30 deg.
would u let me know the mass of the bridge is necessary to consdier to find the tension of the rope ??
I know it is a very simple question...but it is hard for me ..a poor old man...
thanks a lot..
