a) Draw a sketch plan showing stairs, stair treads and adjacent floor areas used for access and working, and on the sketch indicate the distributed loads that should be applied to each of these three components.
b) Sketch and explain what is meant by 'tributary loading' for a one-way support system for a floor slab. Show how to calculate the load per meter of support beam if the support beams are spaced 3000mm apart.
c) Sketch a pin joint, a roller joint and fixed joint; show the kinds of movement that each of these joints allow, and show the forces/moments that each of these joints can support.
suppose 76% of all commuters ride to work in carpools. if eight workers are randomly selected, find the probability that at least 7 will ride in carpools
it carries a uniform service load of 2450 lb/ft in addition to its own weight. material strengths are f'c=4000psi and fy=60000psi .assume a weight od 150 pcf for reinforced concrete.
Submarines change their depth by adding or removing air from rigid ballast tanks, thereby displacing seawater in the tanks. Consider a submarine that has a 700m3 air-ballast tank originally partially filled with 100m3 of air at 1500 kPa and 15oC. For..
