n this week’s forum, please critically discuss the structural characteristics of steel and steel-concrete composite bridges. Include in your discussion the advantages steel offers to the construction of large structures and why it is preferred as a structural material in bridges.

Give the engineering codes of ethics as stated by the US constitution

Hi tried your suggestions for the previous question see link

By the way it works fine when connecting to Windows, Chrome and Edge.

Anyway I'm doing this from home not from the workplace or school.

I also deleted *.gradle directory that didn't resolve the issue.

Using Gradle version 8.4 see picture. Also I noticed when I create new flutter device from command prompt it I get a pubspec.yaml, but when I do it from the latest Android Studio Giraffe it doesn't create a pubspec.yaml. So that's the reason why I create new flutter device form command prompt.

Write a program that asks user enter a sequence of 15 integers and then prints the number of times the user has entered an odd number immediately following an odd number. Arrays are not allowed to appear in your code.

A certain linear system is known to satisfy the following differential equation: 

𝑥'' + 10𝑥' + 100𝑥 = 𝑓(𝑡)
𝑥(0) = 𝑥'(0) = 0

Compute the transition matrix 𝜙 and the covariance matrix 𝑄?

What is civil engineering?

Find which value of k does the system of equations

x - 3y + z = -2

- x + 5y - z = 0

4x - 14y + kz = -5

have infinitely many solutions? For that particular value of k, solve the system of equations for x, y and z.

A solution with parameters may be entered as e.g.:[t,-9/2-6*t,3/2+3*t].

[k,x,y,z] = 

Please Help :) and explain in detail, thank you!

A vehicle is travelling at 72 km/h (20 m/s) when the driver sees a couple walk out on to the road 20m ahead (d=20m). The driver brakes immediately and stops just in time to avoid impact (i.e braking distance is 20m). The vehicle decelerates at a constant, gradual rate without skidding.

If the mass of the car is 1000kg, what was the work and power required to decelerate the vehicle?

A cantilever beam of rectangular cross section (width b=25mm, height h=100mm) is loaded by a force P that acts at the mid-height of the beam and is inclined at an angle ? to the vertical, (see Figure). Two strain gages are placed at point C, which also is at the mid-height of the beam. Gage A measures the strain in the horizontal direction and Gage B measures the strain at angle beta=60 to the horizontal. The measure strains are ?a=125x10-6 and ?b=-375x10-6.

Determine the force P and the angle ?, assuming the material is steel with E = 200 GPa and ? =1/3.

In our model for this class, there are 3 major stages to the System Life Cycle, each with 3 phases. What is the second phase of the second stage?
