The elevator depicted in Figure 9.35 in a planar section, is subjected to a shearing load Vy, as shown. The shear flows in the walls DAC, CBD, and DC are denoted 1. Ф2. Фз, respectively. All dimensions are given in mm. Also, L = 600 and R = 75. 

1. Find m the position of the centroid G and the area S. 

2. Calculate the second moments of area ly and Iz. 

3. Calculate the shear flows iФ1, Ф2, Ф3.
