The traffic light shown in Figure 3 is supported by a system of cables. Points A and B are in a vertical plane which is parallel to x-z plane. Point C is in y-z plane. The traffic light has a mass o
Reciprocal leveling gives the following readings in feet from a setup near A: on A, 2.071; on B, 8.254, 8.259 and 8.257. At the setup near B: on B, 9.112; on A, 2.926, 2.930 and 2.927.
The temperature of steam at the inlets of both turbines is 500 C, and the enthalpy of steam is 3027 kJ/kg at the exit of high pressure turbine, and 2385 kJ/kg at the exti of the low pressure turbine
One method of finding roots of an equation on a computer is the false position method. The idea is that for a function f(x), you find two values, f(x1) and f(x2) such that f(x1)* f(x2) is less than
A 1047 steel plate is subjected to a tensile stress of 120 MPa. Given its fracture toughness is 45 MPa?m and Y = 1, (a) Determine the critical crack length to assure the plate will not fail under st
Describe, with equation and diagram, the flow-discharge characteristic of a long, inclining pipeline that has friction and fitting loss, and a small, positive static pressure head.
For a multi-file project that contains just one class, list and describe each of the files that would be required to implement and test the functions of the class.
Define what is meant by the term compile-time binding and list two other terms that are also used to describe it. Explain why compile-time binding can present problems when implementing polymorphism
If the heading of a member function of a class ends with the word const, then the function members cannot modify the private member variables, but can modify the public member variables.
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.
the present worth of an increasing geometric gradient is $23,632. The interest rate is 10% per year, and the rate of change is 4% per year. If the cash flow amount in year 1 is $3000
Find the present worth of a series of investments that starts at $1000 in year 1 and increases by 12% per year for 20 years. Assume the interest rate is 12% per year.
Determine the payback period for an asset that has a first cost of $40,000, a salvage value of $8000 anytime within 10 years of its purchase, and generates income of $6000 per year.

A w14X74 of A992 Steel has a length of 20 feet and fixed ends. Compute the design compressive strength for LRFD and the allowable compressive strength for ASD.
A nozzle discharges a stream of water with an initial velocity v0 of 50 ft/s into the end of a horizontal pipe of inside diameter d=5ft. determine the largest distance x that the stream can reach.
the velocity of a particle is given by the relation v=100-10x, where v is expressed in meters per second and x in meters. Knowing that x=0 at t=0, determine (a) the distance traveled before the part
