faces of the wedge. Find the vertical deflection of point A due to this given loading.
If G=0.4E, t/c=0.05 and L =2c show that this deflection is approximately
5600p0c2/Et0.
P.9.30 A rectangular section thin-walled beam of length L and breadth 3b, depth
b and wall thickness t is built in at one end (Fig. P.9.30). The upper surface of the
beam is subjected to a pressure which vanes linearly across the breadth from a
value po at edge AB to zero at edge CD. Thus, at any given value of x the pressure
is constant in the z direction. Find the vertical deflection of point A.
