A beam is simply supported at the ends and is continuous over two spans. The left-hand span is 16 ft and the right-hand span is 20 ft. The beam supports a uniform load of 900 plf, which includes its own weight, over the entire 36 ft and also a concentrated load of 10,000 lb applied at a point that is 5 ft from the left-hand end of beam. Determine the bending moment at the intermediate support due to the uniform load only and then the concentrated load only.
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate).

Farmer brown wants to spend exactly 376 dollars on cows,pigs, and sheep and he wants to buy exactly 40 of these animals. If cows are 14 dollars each , pigs are 6 dollars each and sheep are 3 dollars each . How many of each should he buy (buying at le..
A coal-fired power plant produces a net electrical output of 500 MW. The composition of the coal burned is C= 72 %, H= 6 %, S= 3.5 %, O= 6 %, N= 1 %, and ash= 12 % by weight. It's heating value (HV) is 30200 kJ/kg. The net thermal efficiency is 36..
Determine the normal depth in a trapezoidal channel with a bottom width of 6.4 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 85 ft3/s. Manning's roughness factor is 0.025 and the channel bottom slope is 0.001
What do you understand by the term preservation of timber. Briefly explain the different methods of preservation adopted.
Calculate the Air flow required in CFM to transfer 5,396 BTU/Hour in an HVAC duct given that the temperature difference (Delta-T) between the room and the supply air is 21 DegF.
Air can be assumed as a di-atomic ideal gas. Find the final temperature and the amount of work ( in kW) required for air compression at a rate of 100 mol/s , from an initial condition of 1 bar an 25 C to 10 bar; for the following ways.
The beam has an allowable flexural stress of 9 MPa and a much lower allowable shear stress parallel to the grain of 850 kPa. What is the maximum that each of these 2 equal loads can be
Calculate carbonate, noncarbonate, and total hardness Na+ = 27.8 mg/L Cl- = 35.6 mg/L Ca+2 = 48mg/L CO3-2 = 30 mg/L Mg+2 = 12mg/L HCO3- = 61 mg/L K+ = 12 mg/L SO4-2 = 48 mg/L
