Story 1:
Two engineers were designing a bridge using elastomeric bearing pads. One engineer insisted on using the highest quality pads available, while the other wanted to cut costs. The bridge was completed, and the engineer who had insisted on quality pads had a peaceful sleep every night, knowing that his bridge would stand strong. The other engineer, however, couldn't sleep at night, worrying about the possibility of the bridge collapsing.
Lesson: Don't compromise on quality when it comes to structural components. Peace of mind is worth the investment.
Story 2:
A contractor was installing elastomeric bearing pads on a building. He accidentally flipped one of the pads upside down
