To solve this problem, we need to determine the tension in each cable, given that a weight of 600 pounds is suspended from two cables at angles of 30° and 40° to the horizontal. Let’s denote:

- \( T_1 \): Tension in the left cable (angle of 30°).
- \( T_2 \): Tension in the right cable (angle of 40°).

Since the system is in equilibrium, the sum of the forces in both the horizontal and vertical directions must be zero.

### Step 1: Set Up Equilibrium Equations
1. **Vertical Force Balance:**
   \[
   T_1 \sin(30^\circ) + T_2 \sin(40^\circ) = 600
   \]

2. **Horizontal Force Balance:**
   \[
   T_1 \cos(30^\circ) = T_2 \cos(40^\circ)
   \]

### Step 2: Solve for \( T_1 \) and \( T_2 \)

#### Horizontal Equation
From the horizontal force balance equation:
\[
T_1 = T_2 \frac{\cos(40^\circ)}{\cos(30^\circ)}
\]

#### Substitute \( T_1 \) into the Vertical Equation
Substitute \( T_1 \) from the horizontal balance into the vertical balance:
\[
\left(T_2 \frac{\cos(40^\circ)}{\cos(30^\circ)}\right) \sin(30^\circ) + T_2 \sin(40^\circ) = 600
\]

Now, solving this equation will yield the values of \( T_2 \) and \( T_1 \).

Here are 5 related questions to expand understanding:
1. How do angles affect the tension in each cable?
2. What would happen to the tensions if the weight was increased?
3. How does changing the angle on one side impact the tension on the other cable?
4. Why do we use trigonometric functions (sine and cosine) in such tension problems?
5. How does equilibrium help in solving problems involving forces?

**Tip:** Always check both horizontal and vertical equilibrium in tension problems to confirm consistency.

A weight of 600 pounds is suspended from two cables as shown in the figure. What is the tension in the two cables?

Calculate the tension in two cables suspending a 600-pound weight using trigonometry and vector resolution. Solve step-by-step with equilibrium of forces equations, including sine and cosine for angles of 30° and 40°.
