Lab / Structural Analysis
Draw and verify ILs for reaction, shear and moment — quiz yourself or build any determinate beam and generate the exact diagram.
Task: Draw the I.L. for reaction at roller D at 10 m. 10 m Gerber beam — pin A at 0, hinge F at 2 m, roller B at 0 m, roller C at 6.5 m, hinge G at 8 m, roller D at 10 m.
Drag the handles up / down to set your influence-line values, then check your answer.
