Question
Using the method of members (analysis of frames), calculate the resultant pin reactions at A, B and D in the frame shown below. Neglect the weight of the members. Point A and D are pinned supports.
The image shows a diagram of a static structure with multiple members and forces acting on it. Here's a detailed explanation:

- **Support Points:** 
  - Point A and Point D are shown as fixed supports on the horizontal surface.
  - Point C appears to be a point of intersection on a vertical member, above Point D.

- **Members:**
  - Member AB: A slanted member extending from Point A to Point B.
  - Member BC: A vertical member extending from Point B to Point C.
  - The horizontal distance between Point A and Point D is labeled as 6 feet.

- **Dimensions:**
  - The horizontal distance between Point A and Point B is 3 feet.
  - The horizontal distance between Point B and Point D is also 3 feet.
  - The vertical height from Point D to Point C is 6 feet.
  - The horizontal distance from Point B to Point C is 2 feet.

- **Forces:**
  - A downward force of 400 lb is applied at Point B.
  - A horizontal force of 600 lb is applied to the right at Point C.

This diagram can be used to analyze the forces in a static structure and determine unknown forces or moments at the supports and joints.
