The overhead electric hoist C rides along a track on the horizontal beam AB. In addition to the 500-kN vertical force carried by the hoist, the beam also supports the three vertical forces shown.
(a) If x = 5 m, determine the resultant of the four forces carried by the beam.
(b) Determine the distance x for which the resultant of the four forces would act at the center of the span AB.
Calculate the compression resistance of 200 UC 59.5 column which is 3.6 m high (between lateral supports). Both ends of the stanchion are held effectively in position but only one is also restrained in direction. Use grade 43 steel
Each month the speedy dry Cleaning company buys 1 barrel (0.160 m^3)of dry cleaning fluid . Ninety percent of the fluid is lost to the atmosphere and 10 percent remains as residue to be disposed of.
A 1-m3 insulated, rigid tank contains air at 800 kPa, 25?C. A valve on the tank is opened, and the pressure inside quickly drops to 150 kPa, at which point the valve is closed. Assuming that the air remaining inside has undergone reversible adiaba..
H = h - N. At point A, the geoid correction is -100 feet; the ellipse height is 100'. What is the NAVD88 elevation of point A
Argon gas is heated in a constant pressure process from 20.0 to 500.°C. Assuming ideal gas behavior, determine: a. The ratio of the final to initial volumes. b. The change in specific internal energy. c. The change in specific enthalpy of the argon.
Find the area of steel reinforcement required for a concrete T-beam for the following data; f'c = 3 ksi, fy=60 ksi,d=18 in, t= 4.5 in., bw= 10 in., bf= 36 in., 3/4" aggregate, and the section sustains a total factored bending moment 82 k-ft.
The speed limit for a highway is given as "V" in mph. The highway super elevation is given as "e" in ft/ft. The friction between tires and wet pavement is given as "f".

if point D is at (100,100) and the line DE to "E" is 300 feet long at an azimuth of 225 degree , what is location of point E in the XY coordinate system. what is the length and azimuth of the line connection points (100,100) to (300,500)
The coefficient of rolling resistance can be taken to be a constant for all speeds, equal to 0.008. If the cyclist is coasting down a 6% grade, what is the maximum speed attained
An air compressor receives air at 290 K, 100 kPa and brings it up to a higher pressure in an adiabatic process. The actual specific work is 210 kJ/kg, and the isentropic efficiency is 82%. Find the exit pressure and the second-law efficiency.
The lubbock board of city development has decided to ask the city council to construct a tunnel under the snowcapped mountain range east to downtown lubbock so that out of town visitors can reach historic prairie dog town.
