Homework Statement
An object of mass m is suspended from a cable tied to two other cables, each fastened to a supporting beam, as shown below. The tensions in the three supporting cables are T1, T2, and T3. The diagram of the system is available via the link below:

The tension T1 = 1800 N.
I worked out the first three parts, but could not work out parts d) and e)
(a) Determine the horizontal component of T1.
(b) Determine the horizontal component of T2.
(c) Determine the tension T2.
(d) Determine the tension T3.
(e) Determine the mass of the suspended object.
Homework Equations
The Attempt at a Solution
(a) Determine the horizontal component of T1.
Th = 1800cos(60) = 900N
(b) Determine the horizontal component of T2.
Th = 1800cos(60) = 900N (The same component for T2) - The only thing is I do not understand why this is the same - I only knew to calculate it the same because I have the answers given.
(c) Determine the tension T2.
T2 = 900/cos(40) = 1175N
Any help would be appreciated greatly
