Unformatted text preview: Figure 1. The time history of the stress at Stress wave will be reflected with its sign reversed at x = 0 (free end) and with its sign unchanged at x=L (fixed end). Displacement wave will be reflected with its sign unchanged at x= 0 and with its sign reversed at x=L . Explain the reasons why. (3) Sketch the snap shot of the stress wave at t = 7T/8. (4) Sketch time histories of the stress wave as in Fig.2 at x= L for the duration of t=0, 2T.
