Homework Statement


A rope forms a Y.

At the end of the Y hangs a block with a W= 100N
Whole the two upper ends are on the walls.
(Left side) [tex]T{1}[/tex] with an angle of 90 degrees
(Right side) [tex]T{2}[/tex] with an angle of 58 degrees

Find the tension of each rope on the wall.

Homework Equations


No definite formulas

The Attempt at a Solution


[tex]\Sigma[/tex]Fx=[tex]T{1}[/tex]cos90-[tex]T{2}[/tex]cos58=0
Summation of Fy=Tsub2sin58-100=0
=117.92

cos90=0
Which makes the value of [tex]T{1}[/tex] an error.
Where did I go wrong?

Oh sorry...
T1 is measured respect to the vertical
T2 respect to the horizontal

As for the picture ill try to provide but erm its like this:
Your left pointing finger must form a right angle with your right pointing finger such that your nails/tips are touching each other.

Then T1 is attached on your left pointing finger.
And T2 is attach on your right pointing finger.
