Problema di ing strutturale

[Rossy77]

There was a steel beam 50 feet long. The entire 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??


ve lo posto pari pari!!
Grazie!

se ho inteso in modo corretto direi che la frecia della trave in mezzeria è pari a

(PL^2)/(48EJ)

non farmi fare i conti
