Question
The truss system shown below is supported by a pin at A and a roller at G.
- Determine the value of the support reactions at A and G.
- Use method of joint to find forces in member GA and GF. State if these members are in tension or compression.

Transcribed Image Text: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.
