There was a steel beam 50 feet long. The entire Skeith construction crew (total weight: 6000 pounds) was standing at the center of the beam. Assume the modulus of elasticity is 29,000,000 pounds per square inch, the moment of inertia is 850 inches^4, the beam has simple pin connections at either end, and all loads other than the weight of the crew are disregarded.
How much will the beam deflect? Please round to the nearest tenth of an inch.
I don't like math riddles much, and I don't like imperial units much, and the moment of inertia is in a form I'm not familiar with, and my book of equations is at home so..... I can't help at the moment. Maybe later tonight if I remember.
