John enrolled in the Colombian Institute of Technology and Engineering. While studying there, he observed a new building being constructed.  
There was a steel beam 50 feet long. The entire construction crew (total weight: 6000 pounds) was standing at the center of the beam.
 Considering
- the modulus of elasticity is 29 000 000 pounds/square inch
- the moment of inertia is 850 inches ^ four
- the beam has simple pin connections at either end
- and all loads other than the weight of the crew are disregarded.
 
How much do you think the beam will deflect? Round your answer to the nearest hundreth of an inch.
