2 cards from this section. Quick, good the night before a test.
Define a truss.
Think of bridges or roofs.
What type of force is tension?
Consider a tight rope.
What force does a member under tension experience?
Think about a rope being stretched.
True or False: A statically indeterminate truss can be solved solely with equilibrium equations.
Consider the definition of equilibrium.
Design a simple truss with at least 6 members and 4 reactions. Determine if it is statically determinate or indeterminate and explain your reasoning.
Map out the shape and count members and reactions carefully.
If a member is analyzed with a force of -5kN, what does that signify about the assumptions made?
Review how you defined tension and compression within the analysis.
