Your design team has been tasked to test the performance of a new composite beam. Your job is to come up

with different testing scenarios. Each member of your design team comes to you with an idea for test set$-$up

they are shown in the figures below. You roll your eyes; you realize you have a bunch of work to do to figure

out if these test set$-$ups are the same or if they are unique.

First, begin your solution section by explaining how $($in general$)$ you can determine if loading set$-$ups are

equivalent.

Analyze each of the beams shown. Determine which of the loading scenarios are

equivalent $($if any$).$
