The discussion revolves around calculating the tension in two chains supporting a 150N chandelier, making angles of 25° and 30° with the ceiling. The user derives equations based on the equilibrium of forces, ultimately finding T1 to be approximately 158.23 N and T2 approximately 166.14 N. Other participants confirm the calculations are correct and note that the problem is straightforward, lacking a simple method for verification. The consensus is that the user's solution is accurate. Efficient checking methods for similar problems are not discussed.

Alright, so this question was giving me problems and I made one up to solve for practice, but I have no way to check if I did it correctly, so I would appreciate if you could I did it correctly.

Homework Statement


A 150N chandelier is suspended from a ceiling at a single point by two chains that make angles of 25° and 30° with the ceiling. Calculate the tension on each chain.


Homework Equations


T_{1}\cos{25} = T_{2}\cos{30}
T_{1}\sin{25} + T_{2}\sin{30} = 150 N

The Attempt at a Solution


First, I'll label the chain that makes an angle of 25° with the ceiling be T_1 and the chain that makes an angle of 30° with the ceiling be T_2
First I decide to solve for T_2 by using the first equation:
T_{1}\cos{25} = T_{2}\cos{30}
T_{2} = \frac{T_{1}\cos{25}}{\cos{30}}
T_{2} = 1.05T_{1}
Now I substitute this into the second equation:
T_{1}\sin{25} + 1.05T_{1}\sin{30} = 150 N
0.423T_{1} + 0.525T_{1} = 150
After doing simple algebra, I yield:
T_{1} \approx 158.23 N
Now to substitute this to find the tension of the other chain:
T_{2} = 1.05(158.23N) => T_{2} \approx 166.14 N

Therefore, the tensions in the two chains are approximately 166.14 N and 158.23 N. Did I do this correctly? Thanks in advance. Also, what would be an efficient way of checking my solution is correct?

It's correct.
No way of simple checking. The problem is simple itself :)
