For the upper portion of the stiffener AF —

but since -^ must be the same at the point F both in (2) and (5), we find

C,' = C,. ....... 



Integrating (5) :— 



EIy=~lP^x^ + C,x + Ch' (6) 



and since y must be the same in (3) and (6) when x = h, we find C2 ^Cj, 

 and from (6) since y = o when x = o\ €2 = 0. 

 When x=l, M:^ = o, hence from (i) —

When x=l, y=o, .'. from (3) —

Thus we obtain: — Above F — •
