Determine the height h of the rectangular cantilever beam of constant width b in terms of h0 , L , and x so that the maximum normal stress in the beam is constant throughout its length.
a. Calculate the total energy expended in the acceleration. b. Plot a graph of the kinetic energy of the mass against time. c. Plot a graph of the kinetic energy of the mass against distance.
A toothpaste factory situated on a large river disposes of a waste water containing villiamite (NaF) to the river on a continuous basis. The minimum flow in the river is 210 m3/s, and the discharge rate from the treatment plant is 12.5 m3/s.
Determine the minimum length of a sag vertical curve if the grades are ?4% and +2%. Design speed is 70 mph. State assumptions used, consider the following criteria:
a 25-mm diameter steel cylinder 300-mm long falls, because of its own weight, at a uniform rate of 0.1 m/s inside a tube of slightly larger diameter. A castor-oil film of constant thickness is between the cylinder and the tube.
Calculate the initial and final vertical total stress, pore water pressure and vertical effective stress, at the mid-depth of the clay layer, (a) beneath the office block; and (b) beneath the car park
Blocks D and F weigh W1 each and block E weights W2. Determine the sag S for equilibrium. Neglect the size of the pulleys.
The jib crane supports a load of 750 lb from the trolley which rides on the top of the jib. The members of the crane are pinned together at B, E, and F and supported by a short link BH.
The maximum eight-hour average concentration of carbon monoxide (CO) in an urban area is measured to be 17 ppm. The NAAQS is 9 ppmv (equivalent to 10.3 mg/m^3 estimated at P = 1 atm and T=298.25°K).
a a pool of tetrachloroethylene pce has formed above a vertical fracture of circular cross section having an average
Prepare a metes-and-bounds description for the parcel shown in the accompanying figure. Assume all corners are marked with 1-in.-diameter steel rods, and a 20-ft meander line setback from Indian Lake.
For each of the following, draw both the p - v and the T - v diagrams showing the location of the state and write below the diagrams a) what the condition the H2O is in (eg. Superheated vapor), b) which table in the back of the text provides the e..
A brass alloy has a yield strength of 280 MPa, a tensile strength of 390 MPa, and an elastic modulus of 105 GPa. A cylindrical specimen of this alloy 12.7 mm in diameter and 250 mm long is stressed in tension and found to elongate 7.6 mm
