1. A right-angle Cone, with base diameter 2.0m and height 2.45m, isinverted and fixed at the ceiling as shown in Figure 1. The floor height is 2.5m. After thecone deformed (due to the gravity and its own weight), will the cone touch the ground? Please provide your analysis in details. It is given that E = 7 × 106pa and the density ofthe cone ρ = 2000kg/m3.
Two glass capillary tubes of inside diameters of 20 and 13 microns are used to test the capillary rise in an annular cross section .The wall thickness of each capillary is 2 microns .The smaller capillary tube is inserted in the larger one so that..
The rigid bar AD is supported by two steel wires of (1/16)" diameter (E=29x10^6 psi) and a pin and bracket at D. Knowing that the wires were initially taut, determine (a) the additional tension in each wire when a 120-lb load P is applied at B
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
A floor slab has a fundamental bending frequency of 10Hz. A shaker is placed at the centre of the slab for a dynamic testing. The tests confirm that the slab displays a damping ratio of 2% of critical.
The influent flow is 380 Lpcd and the influent BOD5 is 200 mg/L. Pertinent data are: Primary clarifier removes 33% of the influent BOD5, and the state regulatory agency allows a volumetric loading of 0.48 kg BOD5 /(m3.day). Determine the reactor b..
Determine the magnitude of which will cause the reaction at the bearing to be equal to zero. The bearings are in proper alignment and exert only force reactions on the rod. Set = 600 .
The three hinged arch is composed of segments of a circle. Support points A and D are not at the same level. Determine (a) the horizontal and vertical components of reaction at A and D. (b) the shear, thrust, and moment in the arch at point C.
Estimate the amount of Ca(OH)2(s) leached from concrete during a one-year period by precipitation. Assume that the area receives 40 in/yr of precipitation which is in equilibrium with PCO2= 10^-3.5 atm and [SO42-] = 10^-4 M.
Water flows from a large open tank through a sharp edged entrance and into a galvanized iron pipe of a length 1.5 miles and diameter of 4 inches. The water exits the pipe as a free jet at a distance
Pure n-butane is contained in a laboratory cell in which the volume can be varied. The cell is maintained at a temperature of 200°F. The volume is changed until a few drops of liquid n-butane are present. What is the pressure in the cell
Calculate the depreciation using straight-line, double-declining-balance (DBB), and MACRS (current IRS regulation) methods; and tabulate the depreciation schedule.
A valve is now opened and steam at 1Mpa at 473 K is allowed to enter the cylinder until the volume inside increases to 0.04m^3 . Determine the final temperature of the steam and the amount of mass transfer
