Question 1.
What is meant by the term 'truss'?
Show hintHide hint
Think about how triangles support weight effectively.
Question 2.
What does it mean if a member in a truss is compressed?
Show hintHide hint
Consider what happens when you push on a straw.
3Question 3.
What does the method of joints primarily help determine in a truss?
- The stability of the truss
- The forces acting in the members of the truss
- The material properties of the truss
- None of the above
Show hintHide hint
Think about what the method specifically focuses on.
4Question 4.
True or False: If a calculated member force is negative, it indicates that the member is in tension.
- True
- False
Show hintHide hint
Recall what the sign convention tells us.
Question 5.
Given a truss with six members and three joints, if the forces in two members are known, derive the other forces using the method of joints.
Show hintHide hint
Start from joints where you have maximum known values.
Question 6.
Analyze a loaded truss where one member fails and calculate resultant forces in adjacent members.
Show hintHide hint
Refer back to earlier calculations to see how force changes propagate across the truss.
