1. 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.
2. 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.
A beam is loaded and supported as shown in Figure 2. The cross-section of the beam is also shown in Figure 1. Draw neatly the shear force and bending moment diagrams for the beam. Find the locations of maximum shear and bending moment in the beam

A steady-state, well-insulated turbine operates in two stages in series using steam. the first stage has an efficiency of 85% and the second stage 90%. Steam enters the first stage at 400 C and 4 MPa and exits at 1.5 MPa.
The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r= 1.5(2-cos)
consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam.nbspassume length l
A municipality uses green energy and treats 15 × 106 gal/day of a groundwater containing the following: CO2 = 17.6 mg/L, Ca2+ = 80 mg/L, Mg2+ = 48.8 mg/L, Na+ = 23 mg/L, Alk(HCO3-) = 270 mg/L as CaCO3, SO42- = 125 mg/L, Cl- = 35 mg/L.
