A composite beam is composed of a 1/4" steel plate bonded to a wooden member. Ewood = 1.500ksi, Esteel = 29,000ksi
Transform Steel into Wood.
Determine the maximum bending stress for each of the materials in the composite beam if a bending moment of 10 kip-in is applied.
A trapezoidal channel is to design to carry a discharge of 75 m3/s at maximum hydraulic efficiency. The side slope of the channel is 2 H/1 V at the left and slope of right side is 3H/1V. The Manning n value is 0.030.
1-what criteria should zachary use evaluate the project ?2-what assumptions should he make?3-what additional data and
Design a 300 + sl m long variable graded terrace for a land having an average slope of 2 %. Maximum permissible velocity of water in the terrace channel is 60 cm/sec.
The bond has a maturity date of 10 years from now. How much the person must sell the bond for 6 years from now in order to make a rate of return of 10% per year, compounded semiannually is closest.
A vertical bar is known to have dimensions 100" by 1" by 4" priorto application of a load, to have elastic modulus equal to107 psi, and to have a Poisson's ratio equal to 0.3.Suppose the bar is built in at the bottom and a mass of unknownweight is mo..
At what air temperature will exhaled breath condense by self-nucleation. Assume that a saturation ratio of 4.3 is required.
An uncatalyzed reaction has a rate of 4.2 x 10-7 sec-1. When an enzyme is added the rate is 3.2 x 104 sec-1. Calculate the rate enhancement caused by the enzyme.
On a shovel/truck operation the production of the shovel is 293 BCY/h and a job efficiency of 0.75. The trucks used have a capacity of 12 BCY and have a cycle time of 45 min.(excluding loading).
consider the unsteady flow of a fluid in the x direction through a control volume. the linear momentum of the fluid
Incandescent light bulbs have been phased out in the US because they are very inefficient (i.e., they produce a very large amount of heat). A 10 W light-emitting diode lamp (LED) can produce about the same light output as incandescent light bulbs
What is the most significant difference between “free” jets and flows in confined structures (nozzles, pipes, etc.) in terms of formulation of force terms ÓF(i.e. left hand side) of the momentum equation? Assume all flows are subsonic and neglect the..
A rectangular open channel with a width of 10 ft and n = 0.013 conveys a discharge of 300 cfs. The upstream portion of the channel has a slope of 10%, which then abruptly changes to a slope of zero downstream.
