To compute the forces in the two angled rods for an applied force of $F = 1500 \, \text{lb}$ and an angle $\theta = 45^\circ$, we will follow the steps of resolving the applied force into components along the directions of the rods.

Assumptions:

• The system is in static equilibrium, meaning the sum of the forces in both horizontal and vertical directions is zero.
• There are two rods, each at a $45^\circ$ angle to the horizontal. Let's assume the forces in the rods are $F_1$ and $F_2$, and they act along the direction of the rods.

Steps:

1. Resolve forces into horizontal and vertical components: The applied force $F = 1500 \, \text{lb}$ acts vertically downward. Each rod force has horizontal and vertical components due to the angle of $45^\circ$.

2. Equilibrium in the horizontal direction: The horizontal components of the forces in the two rods must balance each other. If $F_1$ and $F_2$ are the forces in the rods: $F_1 \cos(45^\circ) = F_2 \cos(45^\circ)$ Therefore, $F_1 = F_2$.

3. Equilibrium in the vertical direction: The sum of the vertical components of the forces in the rods must equal the applied force $F$: $F_1 \sin(45^\circ) + F_2 \sin(45^\circ) = 1500 \, \text{lb}$ Since $F_1 = F_2$, we can simplify this to: $2F_1 \sin(45^\circ) = 1500 \, \text{lb}$ $F_1 = \frac{1500}{2 \sin(45^\circ)}$

4. Calculate $F_1$: $F_1 = \frac{1500}{2 \times 0.7071} \approx 1060.66 \, \text{lb}$ Since $F_1 = F_2$, the force in each rod is: $F_1 = F_2 = 1060.66 \, \text{lb}$

Conclusion:

The force in each rod is approximately $1060.66 \, \text{lb}$.
