1.How to design a simply supported rectangular concrete beam havingcross section of 20 mm by 40 mm and a length of 3 meters that couldcarry a uniform load of 1000 KN.
2.Compute the maximum service load (25% dead and 75% live)acceptable for a structural tee WT12x38 when used in a truss location where it is braced in the plane of the truss at 20 ft intervals and braced transverse to the plane of the truss at 10 ft intervals. Apply the provisions of AISC-E7 if needed. Use a) A992 steel; b) Fy=65 ksi
A fire hydrant is supplied through a 6 inch cast iron pipe of 16,000 feet length. The total drop in pressure is limited to 35 psi. What is the discharge through the pipe for a water temperature of 80°F ((kinematic viscosity) = 0.93 × 10-5 ft2/sec)
A steel scuba tank is 24 in. long and has an external diameter of 7.25 in. and an internal diameter of 6.7 5in. Say the tank is to carry a pressure of 3000psi . Determine the hoop stress in the tank wall. Determine the axial stress in the tank wal..
At a depth of 4 miles in the ocean the ppressure is 9520 psia. Assume that the specific weight at the surface is 64.0 lb/ft^3 and that the average volume modulus is 320000psi for the pressure range.
Pressure loss in the suction pipe work is directly proportional to water veloicty in the pipe work squared, which is inversely proportional to suction pipe work diameter squared.
Determine the normal stress in the rails when the temperature reaches 48oC assuming that the rails (a) are welded to form a continuous track (b) are 10m long with 3 mm gaps between them.
The compound beam assembly shown is made up of 4 members connected by pins and is supported by hinges/pins at A and E. L= 2.6m (L is the lengthD to E) , and w= 60 (w is the load-lines) .
A concrete dam retaining water has a specific weight of concrete of 23.5kn/m3, what is the factor of safety against sliding & overturning and pressure intensity on the base if coefficient of friction is 0.45
A 6ft wide, 10ft high vertical rectangular gate has its top edge 6ft below the water level. it is hinged along its lower edge. what force, acting on the top edge, is necessary to hold the gate shut
A particle with a mass of 0.5 kg has a velocity of 10 m/s in the x-direction at time t = 0. Forces F1 and F2 act on the particle, and their magnitudes change with time according to the graphical force-time history shown.
Assume that the sludge does not change density during filtration and that liquid removed from the sludge contains no sludge. Using mass-balance method. determine the volume of sludge after filtration.
A roadway has a 4% grade intersecting a -7% grade at at station 18+50.00. The grades are connected by an 800 foot vertical curve. A sign is proposed to be installed at Station 15+00.00. The bottom of the sign is 7 feet above the roadway.
a) Density plot, locating γd(max) and ω opt on the plot b) Zero-air voids curve for the soil on the same plotc) Curve representing S = 70%
