1.A 100-ft steel tape was used to measure a partial baselinedistance. The rear surveyor held 47 ft, while the head surveyorheld .62 ft. What is the distance measured?
2.Using Fy=50ksi, select the lightest available section for the spanand loading shown. Consider moment and shear only and neglect beamweight in all calculations. The member is assumed to have fulllateral bracing.
The beam is simply supported with two sets of loads each 2 ftfrom the reactions.
So there's a live load of 150k and a dead load of 80k 2ft from theleft reaction and 2ft from the right reaction. The total span is16ft... So the distance between the to pair of loads is 12ft..
