A section of a scaffold consists of a plank laid across two supports & extending a distance 'a' on either side of the supports. A mason working at the centre of the plank thinks that he should stack his supply of bricks on the ends of the plank in order to minimize the bending moment in the plank. Is he correct? If equal numnber of bricks are stacked at each end of the plank, for what weight of bricks W, is the maximum bending moment in the plank a minimum? The man weighs W 2.6 We We D.

Determine the deadweight of a 1-ft-long segment of a typical 20-in-wide unit of a roof supported on a nomi- nal 2 × 16 in. southern pine beam (the actual dimensions are _1 2 in. smaller). The __3 4 -in. plywood weighs 3 lb/ft2

The floor of a classroom is to be supported by the bar joists shown. Each joist is 15 ft long and they are spaced 2.5 ft on centers. The floor itself is to be made from lightweight concrete that is 4 in. thick. Neglect the weight of the joists and the corrugated metal deck, and determine the load that acts along each joist.

Hey hows it going, this is a problem from my Structural Analysis course. I am havinig trouble understadning dead loads on girders. The solution is posted on Bartleby. For the dead loading acting on the girder AG, the solution only accounted for the weight of the girder itself. This does not make sense to me because doesnt the girder also support a portion of the concrete slab? Thanks!

Mr. Pine lives on the 13th floor of the Xcel building in Denver. He has decided to extend his existing d1 ft deck (d1 = 3 ft) and add a swimming pool. To get approval for his pool, Mr. Pine must provide information to the building manager. He has hired you to provide: (1) the resultant of the distributed load f(x) lb (2) where the resultant acts relative to point A (3) the reactions at point A due to the addition (distributed load) Given: d2 = 33 ft and f(?) = 215x2 + 3749 lb with x measured from point A
