1. The continuous one-way slab shown below is loaded with a uniform service live load of 80 psf, and a superimposed dead load of 40 psf. Assume the beam width is 16" and use f'c = 5 ksi, and fy = 60 ksi.
a) What is the minimum slab thickness for which a deflection check is not required?b) Find a suitable slab thickness based on a target ω = 0.10.
2. Referring to problem 1, in order to meet a 1-hour fire code rating the slab thickness must be at least 4.00. Based on the information given in problem 1 and with a slab thickness of 4.00".a) Determine the bar sizes and spacing required.b) Determine the cutoff locations for the positive moment steel in each span if alternate bars are cutoff short of the support.c) Determine the cutoff locations for the negative steel if all bars extend the required distance past the support.d) Design the shrinkage and temperature steel.e) Summarize your results with a sketch with reinforcement details.
3. Design the 2-span continuous center T-beam, B2, for the floor syetem shown below. The girders that the beam frames into are all 24" wide. Using fc'= 5 ksi, and fy = 60 ksi. The service life load is 100 psf and there is a superimposed dead load of 40 psf.
Mercury is often used as an expansion medium in a thermometer. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises.
If you have a 0.1M solution of weak acid X (pKa 3.5) and another 0.1M solution of weak acid Y (pKa 4.3), which solution would have the lower pH?
Decaborane, B10H14, was utilized as a fuel for rockets in the 1950's. It ignites instinctively with O2 according to the subsequent reaction: B10H14 + 11O2 ? 5B2O3 + 7H2O
