Show answer
One (perpendicular to surface)
- At what end is a cantilever beam fixed?
Show answer
Fixed at one end, free at the other
- How many equations of equilibrium are available for a 2D structure?
Show answer
Three (sum of Fx = 0, sum of Fy = 0, sum of M = 0)
- How many support reactions must be determined for a simply supported beam?
Show answer
Two (one at each support)
- What is the first step in calculating beam reactions?
Show answer
Apply equilibrium equations (sum of forces and moments)
- What is an influence line in structural analysis?
Show answer
Graph showing how a unit moving load affects structural response at a point
- What principle is used to construct influence lines for indeterminate beams?
Show answer
Mueller-Breslau principle
- For a simply supported beam, what is the shape of the shear influence line?
Show answer
Triangular
- For a simply supported beam, what is the shape of the moment influence line?
Show answer
Triangular with peak at center
- What represents the moving load in influence line analysis?
Show answer
A unit load whose position varies along the structure
- What main use of influence lines helps find maximum reactions or internal forces?
Show answer
Positioning critical loads for worst-case scenarios
- How is an influence line ordinate at a point calculated?
Show answer
Response produced by placing a unit load at that point
