Design a one way slab to support a uniform live load of 300 psf. The beam is simply supported with a span of 20 ft. Use a reinforcement ration ( Ps) of 0.008 Use f'c=3000 psi and fy=60000 psi.
a layer of clay, 5m thick, overlies a deposite of sand, 5m thick, which is underlaid by rock. the water table in the sand is sub-artesian with a level at 2m below fround level. the saturated unit weights of the clay and sand are 21 and 16 KN/m^3 r..
The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e=0.85 and the initial velocity 6 m/s.neglect friction.(teta=70 degrees)
A soil borrow material in its natural state in the ground has a unit weight of 118pcf. Its natural water content is 7%. What is the dry unit weight of this material?
A measurement was recorded as 171.278 m with a 30-m tape that was only 29.996 m under standard conditions. What is the corrected measurement?
Help with a site plan - Design on paper to add some other things in it.
An important dimensionless parameter concerned with very high-speed flow is Mach Number, defined as V/c, where V is the speed of the object such as airplane or projectile, and c is the speed of sound in the fluid surrounding the object.
A soil deposit has a void ratio of 0.89, is the void ratio is reduced to 0.59 by compaction; find the percentage volume less due to compaction.
An old occupational hygiene rule of thumb is that a 10 micrometer (micron) silica particle settles at a rare of 1 ft/min (0.5 cm/s). What is the true settling velocity for such a particle? The density of silica is 2600 kg/cubic meter (2.6 g/cubic ..
A discharge from a power plant cooling tower has a temperature of 81 degrees C and flows into the stream at a rate of 3 cubic meters per minute. What is the temperature in the stream downstream of the cooling tower discharge
Drivers must slow down from 65 miles per hour to 55 miles per hour to negotiate a severe curve on a rural highway. A warning sign for the curve is clearly visible for a distance of 110 feet.
Explain CBR method of pavement design with one example.
If the rocket's decent parachute does not deploy and the rocket lands 340 ft from A, determine the angle (alpha) that vo forms with the vertical, the maximum height h reached by the rocket, and the duration of the flight.
