For your design, you need to make the following choices:

1. Determine the weight of the water that will be supported on each of the main stands. Treat the water load as a uniformly distributed load spanning the whole length of the platform.

2. Decide what the cross-sectional shape of each of the main stands (vertical cross-section) that will be used for your design. It can be either a square, rectangular, circular or an I-beam.

3. Decide on the dimensions of the platforms (horizontal cross-section) so that the support structure can carry the weight from the water tank without axial/crushing material failure and buckling structural failure.

4. Decide the shape of the main stands ranging between square or I-section beam so that the structure will not fail from axial/material failure or buckling structural failure.

2.2 Analytical Calculations

To effectively design the structure, the following are some of the analytical calculations you must show:

1. Reactions at supports: Determine the vertical reactions at the supports of the main stands, assuming no lateral horizontal loading experienced on the structure. Take the weight of the platform to be 5?
