1.An HSS 10×8×3?16 is used as a compression member with one end pinned and the other end fixed against rotation but free to translate. The length is 12 feet. Compute the nominal compressive strength for A500 Grade B steel (Fy = 46 ksi). Use K = 2.0 and LRFD. You are welcome but not required to use the AISC Column Tables or RISA 3D to verify your results.
2.A block with an inclination of 20 degrees has a weight of 60kg, a height of 1.8m and width 1m, static friction is 0.3, what is the force needed and the height (where the force in the box should be) to pish it upwards
Determine the uniform flow depth in a rectangular channel 2.5 m wide with a discharge of 3 m3/s. The slope is 0.0004 and Manning's roughness coefficient is 0.015
A particle has an initial speed of 27m/s. If it experiences a deceleration of (-6t)m/s^2, where t is in seconds, determine its velocity after it has traveled 10 meters. How much time does this take
A venturi water meter with a throatof 6 in registers a presssure head difference of 128 in of water between the inlet and throat. calculate the quantity of flowthrough the meter using a discharge coefficient of.93.
etermine the moment of inertia for the shaded area about the y axis. State the method of integration used and label the diagram accordingly.
on a specific westbound section of highway studies show that the speed-density relationship is u= uf [1-(k/kf)^3.5] It is known that the capacity is 4200 veh/h and the jam density is 210 veh/mi.
a). Determine the state of stresses in the walls and indicate these stresses (including arrows to denote the direction of the stresses) on the element below. b). Then, determine the maximum in-plane shear stress on the wall of the pipe using Mohr's..
For a cantilever beam 20 ft long under a uniformly distributed load of 500 pounds/foot, calculate the deflection v and the slope dv/dx as a function of x by integrating differential equations.
A 30-ft-high, 1-ft-diameter pipe is welded to the top of a cubic container 13 ft * 3 ft * 3 ft2. The container and pipe are filled with water at 20°C. Determine the weight of the water and the pressure forces on the bottom and sides of the contain..
Use this information to estimate the demensions of the biofilter needed to treat 10,000 m^3/hr of air (at 30 C and 1 atm) containing 200 ppm styrene being emitted from a boat- manufacturing plant.
A total of 500 mm of rain fell on a 75 ha watershed in a 10 hour period. Compute the average rainfall intensity and the total volume of rain that fell on the watershed.
consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam.nbspassume length l
