The A-frame shown is pin-connected at A, B, C, and D. The surface at E is level and frictionless. Calculate the reaction at E and the reaction components at the pins.

The image depicts a structural framework consisting of several members joined together, forming a truss-like assembly.

**Components of the Structure:**

1. **Members:**
   - The structure consists of five members: AB, BC, CD, DE, and AE. These are represented by straight lines connecting various joints in the diagram.

2. **Joints:**
   - **A:** The leftmost joint, secured with a pin connection to the ground.
   - **C:** The top joint, where the two inclined members (BC and CD) meet.
   - **B:** A joint below C on the left side, connecting member AB to BC.
   - **D:** A joint vertically aligned with B on the right side, connecting member CD to DE.
   - **E:** The rightmost joint, resting on a roller support.

3. **Supports:**
   - **Pin Support at A:** This allows rotation but no translation in any direction.
   - **Roller Support at E:** This allows horizontal movement but restrains vertical movement.

**Forces Applied:**

1. **External Forces:**
   - A horizontal force of 2 kN is applied at joint B, directed to the right.
   - A vertical force of 3 kN is applied at joint D, directed downward.

**Dimensions:**

- The vertical distance from A to B is 5 meters.
- The vertical distance from B to C is 5 meters, totaling 10 meters from A to C.
- The horizontal distance from A to E is 10 meters, composed of 5 meters from A to B, 2 meters from B to D, and 3 meters from D to E.

This framework illustrates a typical problem in structural analysis, where one must calculate the internal forces within each member and the reactions at the supports under given load conditions.
