To solve the problem, let's first analyze the information given in the image. The problem asks us to:

1. **Determine the magnitude and direction of the resultant force.**
2. **Determine the moment at point A.**

### Step-by-Step Solution

#### Step 1: Identify the Forces

From the image, we have the following forces applied to the structure:
- A vertical force of **200 lb** acting upward at point A.
- A force of **100 lb** acting horizontally to the right at point C.
- A force of **50 lb** acting downward at point B.
- Another force of **70 lb** acting at an angle of **30 degrees** to the horizontal at point D.

#### Step 2: Determine the Resultant Force

To find the resultant force, we need to resolve all forces into their x (horizontal) and y (vertical) components:

1. **Vertical components (Fy):**
   - \( F_{A_y} = 200 \) lb (upward)
   - \( F_{B_y} = -50 \) lb (downward)
   - \( F_{D_y} = 70 \sin(30^\circ) = 70 \times 0.5 = 35 \) lb (upward)

   Total vertical force (Fy):
   \[
   F_y = F_{A_y} + F_{B_y} + F_{D_y

For the given force system, determine the magnitude and direction of the resultant force. Determine also the moment at point A.

Analyze the force system to find the magnitude and direction of the resultant force and the moment at point A. This problem involves force resolution, vector components, and calculating moments, essential for statics.
