Figure 13.18 shows proposed curb locations, together with offset stakes for the north-side curb. The straight section of curb begins at station 0 + 15 and ends at station 2 + 10. With the aid of a sketch, show how these two chainages were determined.
Draw the three most popular brick bonds from memory.
A speedboat on hydrofoils is moving at 20 m/s in a freshwater lake. Each hydrofoil is 3 m below the surface. Assuming, as an apporximation, frictionless, incompressible flow, find the stagnation pressure(gage) at the front of each hydrofoil.
A 300 mm diameter pipe is placed in a 3 m deep rectangular trench that is 0.60 m wide. The trench is backfilled with clay that has a bulk unit weight of 18.8 kN/m3. Compute the dead load due to backfill that the pipe must support.
A proposed square footing carrying a total load of 900 kips is to be constructed on a uniform thick deposit of cohesionless soil. The soil's unit weight is 135 pcf, and its angle of internal friction is 38 degrees.
The elevator of a large building is to raise a net mass of 400 kg at a constant speed of 12 m/s using an electric motor. Minimum power rating of the motor should be
Problem 1: The Steel beam has the cross-sectional area shown and the steel has elastic constant of E = 210 GPa, v = 0.3. The thickness of vertical wall is 6 mm and those for horizontal are 4 mm. For the flange,b1 = 60 mm and b2 = 120 mm. the heigh..
A quality of water within a piston-cylinder assembly executes a Carnot power cycle. During isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. The vapor then expands adiabatically to a pressure of ..
A suspended solid particle of density 2200 kg/m3 is moving at 0.25 m/s of horizontal and 0.15 m/s of vertical velocity respectively in a sedimentation tank. If the depth of the tank is 2.0 m what should be the length of tank to trap the particle i..
Describe three different ways to generate random numbers and explain for each of the four properties (from (a0) which is “yes” and which is “no”.
The hypothetical velocity distribution in a horizontal, rectangular open channel is V=0.3y (m/s), where V is the velocity at a distance y (m) from the bottom of the channel. If the vertical depth of flow is 2 m and the width of the channel is 4 m,..
Restrictions in landing slots at Heathrow airport in London allowed the purchase of five landing/takeoff slots, one per weekday (Monday through Friday). The carrier does not intend to offer weekend service.
A particle travels along a path defined by the parabola y=0.5x^2. If the component of velocity along the axis is Vx=6t with t in seconds. determine the particle's distance from the oriigin
