So, which is the best design? The only difference between the three designs are the angled support members at 30\u00b0, 45\u00b0, and 60\u00b0 to the vertical uprights<\/strong>.<\/p>\n

\"\"<\/a><\/p>\n

At first glance, this one may seem like a simple question, but when you dig into it deeper from an engineering and design perspective, the answer is not so obvious. This question is relevant because it\u2019s similar to the one that we as designers and engineers may have to answer on a daily basis.<\/p>\n

When evaluating multiple designs to find the optimal or the best design, key decisions can be made based on having a set of evaluation goals, or in other words, design performance criteria. In the frame design challenge, the strength<\/strong> of the frame and the frame vertical displacement<\/strong> due to the bending load can easily be used to pick which design works the best.<\/p>\n

Here is the comparison of results between the three designs using plain carbon steel as the material.<\/p>\n

The 60\u00b0angled frame has the best performance in terms of a safety factor of 2.6 and a vertical deflection of 0.57 mm. Between the good and the best designs, we see a performance improvement of about 40 percent in terms of smaller deflection and about a 13 percent stronger frame! <\/strong><\/p>\n

The good news is that now this best design can be subjected to further iterations to answer the following questions:<\/p>\n
