1
The beam is simply supported at both ends, and w(x) = wo (constant) and
the length is L. what is the deflection of the beam.
2
The beam is embeded at both ends, and w(x) = x and the length is L. what is
the deflection of the beam.
3
The beam is embeded at x = 0 and free at x = L, and w(x)=sin(拍X)
and length is L. whatis the deflection of the beam.
1.y(0)=0 y''(0)=0 y(L)=0 y''(L)=0
2.y(0)=0 y'(0)=0 y(L)=0 y'(L)=0
3.y(0)=0 y'(0)=0 y''(L)=0 y'''(L)=0
這樣設條件對嗎??
