physics help i still dont get it

posted by .

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

    ill try it but i have no idea how you get the angle appreciate it

  • physics help i still dont get it -

    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

    Thank you so much but its just upsetting me i cant figure it out

  • physics help i still dont get it -

    i forgot to divide the sqrt by 2.5 to get .116 sorry but thank u
