You are given a body with no body forces and told that the stress state is given as: ⎡ ⎣ 3αx 5βx2 + αy γz3 5βx2 + αy βx2 0 γz3 0

Lady bird [3.3K]

Answer:

This doesn't represent an equilibrium state of stress

Explanation:

∝ = 1 , β = 1 , y = 1

x = 0 , y = 0 , z = 0 ( body forces given as 0 )

Attached is the detailed solution is and also the conditions for equilibrium

for a stress state to be equilibrium all three conditions has to meet the equilibrum condition as explained in the attached solution

High strength steels are being used to reduce weight on cars. Explain why using a high strength steel would allow you to reduce

gulaghasi [49]

Engaging the frequently tough requirements of vehicle safety, weight reduction for combustible economy, and manufacturability has influenced the steel industry to create a unique variety of 'super steels' for the automobiles of the future.

<h3><u>Explanation</u>:</h3>

• That steel, though, is far more advanced than the materials of just a few years ago.

• At the forefront of these is Advanced High Strength Steel, AHSS, developed by World Auto Steel’s member companies, which is demonstrating to be something of a vision in automobile production.

• The standard engineering trade-off in steel preference involves considering the need for ultimate strength against flexibility and work-ability – stronger steels tend to be stiffer and less ductile, making them more difficult to develop into cars and more laborious to weld.

• AHSS can retain greatest of the ductility and work-ability of lower grades of steel, while offering much greater strength.

• Where a typical mild steel might have a tensile strength of 300MPa, AHSS can exceed 1500MPa while retaining a highest elongation of 25%, compared to about 40% for mild steel. The intrigue is in the micro-structure, containing a martensite, bainite, austenite phase rather than ferrite, pearlite, or cementite.

You assume the following relationship: u=x1αx2β. You take the following monotonic transformation: v=ln(u). You get a linear rela

ollegr [7]

Answer:

MRS = -2.23 (x2/x1)

Explanation:

The concept of Marginal rate of substitution(MRS) is applied here. MRS occurs when a consumer is willing to give up a good at the expense of another whilst still maintaining the same utility. The principle of partial differentiation is mostly applied in MRS Calculation.

From MRS = -(MUx/MUy)

The steps are as shown in the attachment

What is the last item on the vehicle starting checklist

larisa86 [58]

The last item on the vehicle starting checklist before a driver begins to travel is for the driver to release the service brake.

<h3>What does it mean to release the brake?</h3>

The Release Parking Brake message implies that your parking brake is said to be currently engaged and as such one needs to release the parking brake before one can be able to drive the vehicle.

Therefore, The last item on the vehicle starting checklist before a driver begins to travel is for the driver to release the service brake.
