Calculate (a) the magnification factor (b) the amplitude of the steady state response and (c) state if the steady state response is in phase or out of phase for
(1) P19.18 if a vertical (downward) force of P=4 sin(20t) (lb) is applied to the 75lb block
A 75-lb block is supported by the spring arrangement shown. The block is moved vertically downward from its equilibrium position and released. Knowing that the amplitude of the resulting motion is 2 in.,
Determine (a) the period and frequency of the motion, (b) the maximum velocity and maximum acceleration of the block
Determine the excess pressure inside an 0.5-in-diameter soap bubble floating in air, given the surface tension of the soap solution is 0.0035 lb/ft.
Gas is flowing in a long 9-in-diameter pipe from A to B. At sectionA the flow is 0.65 lb/sec while at the same instant at section Bthe flow is 0.72 lb/sec. The distance between A and B is 750 ft.
The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
If the elastic values of Bus service demand with respect to fare & headway are -0.35 & -0.7 respectively. A Bus service system which currently carries 56,000 passengers per day plans
Construction dewatering plays are very large role in the todays construction arena. Discuss the role water conditions plays in the planning and design of a temporary earth support system.
Determine the young's modulus for a metal whose elasic limit isone half of its UTS. The material has a strain of 0.002 at theelastc limit and a gauge length of 50mm. The UTS of the metal is300 MPa.
Name three types of metamorphic foliations, and draw a small sketch that shows a situation. Where a metamorphic foliation could cause problems in an excavation.
write solution in a organized and easy to follow matter. Will rate life saver for diagram or picture.Water leaves a treatment plant in a 500-mm diameter ductile iron pipeline at a pressure of 600 kPa
A certain element of soil is subject to a mean normal stress of 420 kpa and a deviator stress of 280 kpa. The major principal plane is rotated 30 degrees counterclockwise from horizontal.
The surface area of clay particles can be determined by measuring the number of adsorbate molecules it takes to form a monolayer. The adsorbate molecules used for these measurements are usually N2 gas, therefore partial pressure "P" is used instea..
A single-scoop ice cream cone is a composite body made from a single scoop of ice cream placed into a cone. Assume that the scoop of ice cream is a sphere with radius = 3.36cm that is placed into a 9.90cm tall cone. The interior height of the cone is..
Compute the electrical conductivity of a 7.4-mm diameter cylindrical semiconductor specimen 28 mm long in which a current of 0.20 A passes in an axial direction.
