Cylinder with radius "R" and mass "m" is layed between 2 no-mass poles. (see Drawing)
The poles are connected on the mutual point C and with a string between E and D.
The angle between the legs of the poles is "alpha", the distance CD is "d", and the distance CB
is 1.
What is the tension T of the string ?

i dont want to do all the calculations, but i guess it would be same as m*g (m mass of the cylinder.
