2 cards from this section. Quick, good the night before a test.
What is the key function of a truss element?
Think about what force types truss elements are designed to resist.
What is a key property of the stiffness matrix?
What is the main purpose of this matrix in structural engineering?
What is the primary load that a truss element is designed to support?
Consider the direction of forces that trusses resist.
True or False: A truss element has multiple degrees of freedom at each node.
Think about how many ways a node can move in a truss structure.
Assume a truss composed of two members forming a right triangle, with lengths of 3m and 4m, and a vertical load of 10,000N at the junction. Calculate the internal force in each member using the principles of truss analysis.
Draw a free-body diagram to visualize the forces acting on the truss.
A truss member of length 6 m with a cross-sectional area of 0.02 m² and modulus of elasticity 210 GPa is subjected to a tensile load of 50 kN. Calculate the elongation of the member.
Pay attention to make sure all units are consistent when substituting into the formula.
