A Simply supported rectangular, tension-reinforced beam is to be designed for dead load of 0.75 k/ft plus self weight and service live load of 2.0 k/ft, with a 30 -ft simple span. Material strength will be fy = 60 ksi and fc = 5 ksi for steel and normal weight oncrete respectively.

Startthe design of the beam dimensions using the rules of thumbs in class. The total beam depth, h, must not exceed twice the width.

Calculate the required beam dimensions and tensile steel requirement (As required) to carry the Maximum moment found at mid span. Start with a steel ratio of half of "usable rho" in Table 27.2 in the text. Use ACI load factors and strength reduction factors. The effective depth (d) may be assumed at 3 inches less than the total depth (h).

Draw a sketch clearly showing spacing, cover, and bar locations.

A spring has one of its ends fixed, and a force of 15 N stretches it 20cm. A mass of 4 Kg is attached to the end of the spring, and the system is set in motion with initial position = 60 cm and initial velocity = 1.5 m/s.

(a) Find the spring constant. 
(b) Write a problem of initial conditions for spring stretching, in meters. 
(c) Solve the problem posed in (b). 
(d) Write the solution in the form x = rsen(ωt + θ). 
(e) What are the amplitude, frequency and period of movement?

The phase relations in the system of CaO-SiO2 show the possibility of C3S formation at temperature range from 1250 to 2150 °C. However, to produce pure C3S phase, generally, over 1600 °C is suggested, which is considerably higher than the 1450 °C in an industrial kiln. Explain why it is possible to form C3S at this lower temperature in the industrial kiln.

A two-lane minor road intersects a two-lane major road at 90 degrees, forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 40 ft from the minor road. If the speed limit were 45 mi/h on the major road and 25 mi/h on the minor road, determine the minimum distance that the building can be located from the centerline of the outside lane of the major street.

Question One

Creep is one of the deformations that occurred in a concrete structure.

Give one example that can be associated with creep problem in the concrete structure. Define what is a creep and discuss how the creep occurred in the chosen example.

until now there is no response.

For this deliverable, you will evaluate software suitability, human systems integration, survivability,

and interoperability issues for the SWARM Unmanned Aerial Vehicle (UAV) system. Provide a report that summarizes your findings for this analysis.

5.1 Software suitability

For this task, in the Maier and Rechtin text, in other course material, and your general knowledge of software.

Identify three software suitability characteristics that you select as the highest priority for the UAV System. For each characteristic, justify why you selected it as a high priority for this system.

For each software suitability characteristics identied above, construct a well-written sample software suitability requirement that could be included in the system requirements for the UAV SWARM system.

For each of your software suitability requirements, discuss the test and evaluation activities needed to provide the basis for the final acceptance of the SWARM UAV system. Include estimates of the cost, duration, personnel, equipment, ranges, and other factors necessary for test, evaluation, and acceptance.

For each estimate, provide a rationale.

5.2 Usability, survivability, & interoperability

Identify one potential issue for each of the following ilities that applies specifically to the SWARM UAV system, and discuss a feasible solution to address the issue

usability

survivability

interoperability with an external system

5.3 Overall suitability

Clearly state you nal conclusion about the overall suitability of the UAV SWARM system as a research platform. Provide justication of your nal conclusion by using the key results from your previous analyses done for the system.

What are the Engineering Ethical issues Such as (such as rights and obligations; conflict of interest; professionalism and mentoring; confidentiality; whistleblowing; bribery, fraud, and corruption) That Leads to the collapse of the WEST GATE BRIDGE in Melbourne Australia and how these can be prevented? Please write in essay style. I will give you thumbs up just do it.
