A picture of width 43.0 cm, weighing 52.0 N, hangs from a nail by means of flexible wire attached to the sides of the picture frame. The midpoint of the wire passes over the nail, which is 2.50 cm higher than the points where the wire is attached to the frame. Find the tension in the wire.

sinα =2,5/sqrt{2.5²+(43/2)²}

m•g=2•T•sinα

T=m•g/2•sinα

sinα =2,5/sqrt{2.5²+(43/2)²} =0.116

m•g=2•T•sinα

T=m•g/2•sinα =52/2•0.116 =225 N
