A monolithic reinforced concrete floor is to be composed of rectangular bays measuring 6 m x 7.5 m. The floor is to designed to carry a service live load of 5 KPa, floor finish of 1.5 KPa, and ceiling load of 1 KPa, in addition to its own weight. Design the corner floor panel slab using fc’=21 MPa, fy = 400 MPa, and concrete unit weight of 23.54 KN/m3.

After graduating from this university you have decided to establish a contractorship company to do some building constructions. Your first job is to construct 10 similar reinforced concrete buildings with four stories each. The total area of all the buildings is 16,000m2 . You can find sufficient number of formwork carpenters to erect any kind of formwork materials. On the market both timber and steel formwork materials are available.
•Make an analysis on which type of materials you are going to buy for that construction job.
•From internet you will find the addresses of formwork materials manufacturers / suppliers and get prices.
•Explain the advantages and disadvantages of buying timber or steel type formwork materials.
•Make an analysis for selection of formwork materials.
•Decide to buy one of them and explain in detail why you have selected that one.

A moving belt system is to be used to fransfer lubricant from a sump to the point of application. The working length of the belt is assumed to be straight and to be running parallel to a stationary metal surface. The belt speed is 200 mm/s, the perpendicular distance between the belt and the metal surface is S mm, and the belt is 500 mm wide. The lubricant is an oil, having an absolute viscosity of 0.007 Ns/m2• Estimate the force per unit length of belt and the quantity of lubricant discharged per second. If the relative density of the oil is 0.891, what is the kinematic viscosity of the oil?

Determine the maximum allowable span of nominal 2x4 wall forms studs carrying a design load of 1000 psf. Stud spacing is 16” on center. Use the allowable stresses for Douglas Fir from Table 13-8 and 7 day load duration. Assume that studs are continuous over 3 or more spans. Limit deflection to l/360 of span length. Based on the maximum allowable span, check for crushing of studs on double 2x4 wales. Conditions are dry.

Convert the water quality data below to make a diagram allowing
you to quantify the 4 categories of hardness for the water, all in
mg/L as CaCO3. Also use units of mg/L as CaCO3 to determine the
amount of CaCO3 formed, then convert it to meq/L and mg/L. Finally,
if the influent flow rate is 17 MGD, determine how many pounds per
day of CaCO3 are produced. Attach all work and fill in the blanks
too*.
Mg2+ = 17 mg/L
Ca2+ = 63 mg/L
HCO3- alkalinity = 80 mg/L as CaCO3
CaCH = _____________ mg/L as CaCO3
MgCH = _____________ mg/L as CaCO3
CaNCH = ____________ mg/L as CaCO3
MgNCH=____________ mg/L as CaCO3
CaCO3 = ___________ mg/L as CaCO3
CaCO3 = ___________ (meq/L)
CaCO3 = ___________ (mg/L)
CaCO3 = ____________ (lbs/day)
