Bars A and B have cross-sectional areas of 400 m2 and a modulus of elasticity of 200 GPa. A gap exists between bar A and the rig
NISA [10]

Answer:

axial stress in bar B = 25Mpa.

Deformation of bar A = 0.4mm.

Explanation:

PS: Kindly check the attached picture for the diagram showing the two bars that is to say the bar A and the bar B.

So, we are given the following data or information or parameters which we are going to use in solving this particular question or problem. Here they are;

The cross-sectional areas of Bars A and B =  400 mm2, the  modulus of elasticity of  bar A and bar B = 200 GPa, applied force = 10kN.

STEP ONE: The first step is to determine or calculate the axial stress in bar B. Therefore,

Axial stress in bar B = 10 × 10³ ÷ 400 × 10⁻⁶ = 25 Mpa.

STEP TWO: The second step here is to determine or calculate the deformation of bar A. Therefore,

The deformation of bar A = 20 × 10³ ×1.5 ÷ 400 × 10⁻⁶ × 200 × 10³ = 0.375 mm.

What is the first step in the problem-solving process, as well as in the engineering design process?
DENIUS [597]

Answer:

C. Brainstorm

Explanation:

<em>Brainstorming refers to thinking and developing ideas and solutions to problems</em>. It involves a free-thinking approach and putting oneself in the context of the problem you are attempting to solve. You can use the empathy maps to combine ideas from interviewing other people on the same. This stage is followed by defining the problem, concept generation, developing a solution, constructing a testing a prototype, evaluating the solution and finally presenting the solution.

Answer choice A is incorrect because it is the last stage .

Answer choice B is incorrect because it is the second stage.

Answer choice D is incorrect because it is step 5 and 6.

Find (i) the lateral or curved surface area of a closed cylindrical petrol storage tank that is 4.2 m in diameter and 4.5 m high
aleksklad [387]

Answer:

  (i) 59.38 m^2

  (ii) 64.77 m^2

Explanation:

<h3>(i)</h3>

The lateral area of a cylinder is ...

  A = πdh

  A = π(4.2 m)(4.5 m) = 18.9π m^2 ≈ 59.38 m^2 . . . tank wall area

__

<h3>(ii)</h3>

If that represents 11/12 of the steel used, then the steel used is ...

  (12/11)(59.38 m^2) ≈ 64.77 m^2 . . . steel used
