To determine the distance between points X and Y on the opposite sides of a river, a surveyor measures a distance of 300 m between points X and Z, where Z is set on the same side of the river as X. Angle X-YZ is measured to be 85°30 and angle Z-XY is measured to be 35°45. Compute the distance XY.
Doug decides to use a turkey fryer to prepare the Thanksgiving turkey. Due to cold weather, he prepares the turkey with the door closed, limiting air exchage (Q) within the 40 m3 garage to 0.2 m3 min-1
A 6 inch X 4 inch rectangular beam is subjected to a maximum shear force of 1900 lbf. Determine the shear stresses at each of the following points on the beam cross section:
The mean annual precipitation for a 325 mi2 watershed is25 inches. Assume that 20% of the annual precipitation reachesthe watershed outlet as streamflow. Determine the meanstreamflow rate in ac-ft/yr
When a particle falls through the air, its initial acceleration a=g diminishes until it is zero, and thereafter it falls at a constant or terminal velocity v_f . If this variation of the acceleration can be expressed as a=(g/v^2_f)(v^2_f-v^2)
Determine (a) the final mixture temperature and (b) the final mixture pressure.
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
A model of a submarine, at 1:15 scale, is to be tested at 0.8 ft/s in a wind tunnel at standard at mospheric pressure, while the prototype will be operated in seawater. Both the air and water are at 10 C (50 F).
Suppose in 100 years energy consumption is still 330 Ej/yr, but coal supplies only 20 percent of total demand, natural gas supplies 30 percent, and oil 10 percent. The remaining 40 percent of demand is met by noncarbon-emitting sources.
You are an engineer working for a utility company. Your project team is designing the power distribution (overhead wires) in a new subdivision. Shown in the following is the last pole along one of the streets. For this dead end configuration you have..
The 25-mm thick rectangular bar is subjected to the axial load of 10 kN. If the bar is joined by the weld, which makes an angle of 60° with the horizontal, determine the shear stress parallel to the weld and the normal stress perpendicular to the ..
A factory discharges its waste into a river upstream from a lake. The discharge release rate is 2 kg formaldehyde per day. The decay is a first order process with a decay rate of 0.000005/s. The waste is discharge into the river 30 km upstream from t..
