Determine the hydrostatic force on one side of a vertical clrcular gate of diameter 1.5m when its centre is immersed at a depth of 6m neto-w tne free surface of water in a reservoir. Determine also the depth from the surface to the line of action of this force. you are reminded that the second moment of area for a circle about its centroid is given as:
Ic - nd4 /64 where d = diameter.
Explain briefly what additionalforce you would need to calculate if the
gate were located in an embankment inclined at an angle 0 from the
At the instant when angle theta= 50 degree, the horizontal guide is given a constant upward velocity v0 = 1.3 m/s. For this instant calculate the force N exerted by the fixed circular slot and the force P exerted by the horizontal slot on the 0.60..
Break Even Stripping Ratio (BESR), Given an underground total mining cost of $8.85 per tonne, surface mining costs of $2.95 per tonne of ore, and surface mining stripping costs of $1.75 per tonne of waste
The bottom of piezometers A and B are on the same flow line and 1000 m apart. The bottom of piezometer A is at 130 m and its water level is 160 m. The bottom of piezometer B is at 100 m and the water level is 150 m.
For Vectors A=(i + 2j - 3k) and B=(4i - 5j + 6k), determine:
A gas bubble is formed at the tip of a small tube which is completely immersed in a large body of liquid. The bubble remains in contact with the open end of the tube in a way that allows us to control the pressure P inside the bubble.
This causes the student to begin to rotate. Find the student's final angular velocity. The moments of inertia of the wheel and of the student are 0.313 kg · m2 and 2.09 kg · m2 respectively.
A spillway carries a discharge of 22.5 m^3/sec with the outlet velocity of 15 m/sec at a depth of 0.2m. Select an adequate USBR stilling basin and determine the sequent depth, the length of the hydraulic jump and energy loss.
The 5-m long cantilever beam using a W410 x 67 standard wide flange section has a distributed load of 1200 N/m placed on it. It is also supported by a cable at B, of length 2 m with a 7 mm2 cross sectional area. What is the force in the wire
