Question 4

Fig. 4 shows a pictorial view of a shell structure. Also shown are the outline plan, elevation and end elevation of the structure. The surface is generated, as shown, by moving a straight line element parallel to the horizontal plane, so that it is always in contact with the vertical line DE and the semi-circle ABCS.

Draw the given plan, elevation and end elevation and determine the true shape of the sections R-R and S-S through the structure.
