Question

The truss system shown below is supported by a pin at A and a roller at G.

  1. Determine the value of the support reactions at A and G.
  2. Use method of joint to find forces in member GA and GF. State if these members are in tension or compression.

 

The diagram illustrates a truss system with several joints and members. The truss is anchored to a wall at points A and G. 

- Horizontal Members: AB, BC, CD
- Vertical Members: AG
- Diagonal Members: AF, BE, CE, ED, FG

Dimensions:
- Each horizontal section (AB, BC, CD) measures 4 feet.
- The vertical height from point G to point A is 8 feet.

Forces:
- There is a 1500 lb external load applied at point D at a 60° angle downward to the right.

Triangle and Support:
- Point G and A are supported by fixed pin connections suggesting these are reaction points that prevent movement.
  
This is a typical structural analysis scenario used to teach students about forces in a truss system and how they are distributed across different members.
