1. The figure shows the cross section of a rectangular gate 4 m high and 6 m long (perpendicular to the paper) which blocks a fresh-water channel. The gate has a mass of 8.5 Mg and is hinged about a horizontal axis through C. Compute the vertical force P exerted by the foundation on the lower edge A of the gate. Neglect the mass of the frame to which the gate is attached.
2. The horizontal steel shaft with two diameters is welded to the fixed block at A. Construct the dia-grams of shear and moment in the shaft due to its weight. Determine the values of the shear force and bending moment at the discontinuity in diameter.
a spherical tank aisi 302 stainless steel has an outside diameter of 40cm and a wall thickness of 2cm. it contains
assume that the heat treatment supervisor in charge of processing the some gears is on an economy program directed
Air is compressed steadily in a compressor from 100kPa and 300 K to 1 Mpa and 500 K. The compressor is not well insulated and a heat loss of 40 KJ/kg occurs during the process. Assuming the changes in kinetic and potential energies are negligible, de..
The lift force on a Wortmann air foil is measured five times under the same experimental conditions. The acquired values are 10.5N, 9.4N, 9.1N, 11.3N, and 9.7N. Assuming the true lift force is 10.7N; calculate a) the systematic error, b) random error..
consider a metal that is subjected to cold working by rolling it to a lesser thickness or hammering it. a would you
A fire truck draws water from an open constant-level reservoir through a hose of 0.2 ft2 cross section. The water is discharged from the pump through another 0.2 ft2 hose to a surge tank pressurized to 120 psig with air at the top. The pump adds 970 ..
Find the shear flow distribution in the thin walls of the section. All of the walls have a thickness of 8 mm. All ,the dimensions shown are in mm and are to the medians of the flanges and webs. Locate the shear center relative to the vertical web.
A rigid tank contains 2 kmol of N2 and 6 kmol of CH4 gases at 200 K and 12 MPa. Estimate the volume of the tank using Amagot’s Law and the generalized compressibility chart
With the aid of diagram, briefly explain how collector current is obtain if the transistor is connected in c-e configuration. How is phase reversal achieved between the input and output in the circuit
a 25-cm diameter oil line is buried with its centerline 60 cm below the ground. assuming a soil temperature of 10
a gas in a piston-cylinder device is compressed through a combination of external force on the piston and cooling in
Superheated steam at 600 C and 4000 kPa is fed into a turbo expander at a rate of 10 kg/s. The steam expands and leaves the expander at 500 kPa pressure and 300 C. It is known that there is a heat loss of 50 kJ/sec. This heat loss can be assumed to t..
