Determine the force in each member of the truss. Stale if the members are in tension or compression. Prob.6-3

Fofino [41]

When a force is applied to a member and it is pointed at a joint, the member is in compression. When a force is directed away from a joint that the member is attached to, it is said to be in tension.

<h3>What is tension?</h3>

The pulling force transmitted axially by a string, rope, chain, or other similar object, or by each end of a rod, truss member, or other similar three-dimensional object, is referred to as tension in physics. Tension can also be described as the action-reaction pair of forces acting at each end of the aforementioned elements. Tension, the opposite of compression, is conceivable.

To measure tension as a transmitted force, an action-reaction pair of forces, or a restoring force, the International System of Units uses newtons (or pounds-force in Imperial units). At the point of attachment to the objects to which the string or rod is connected, the ends of a string or other object that transmits tension will exert forces in the direction of the string.

The time for 65% consolidation for a 19-mm clay specimen (drained at top and bottom) in the laboratory is 10 minutes. How long w

Elden [556K]

Answer:

456.2 days

Explanation:

Cv = tv x d²/t

For v>69%

We have tv = -0.933log(1-0.65)-0.0851

= 0.4254-0.0851

= 0.340

d² = (19/2)²

= 90.25

Cv = 0.340x90.25/10

= 3.0685mm²/min

At 40% consolidation

Tv = pi/4 x 0.4²

= 0.126

t = Tv x d²/cv

= 0.126x(4000)²/3.0685

t = 656998/60*24

= 456.2days

So it is going to take 456.2 days for a 4-m thick clay layer in the field to undergo 40% consolidation under the same pressure increment.

Anvisha [2.4K]

Answer:

Your stratified squamous epithelium is difficult to penetrate!

Explanation:

The epithelium is the tissue formed by one or several layers of cells attached to each other that cover all the free surfaces of the organism, and constitute the internal lining of the cavities, organs, hollows, ducts of the body and skin and also form the Mucous and glands. The epithelia also forms the parenchyma of many organs, such as the liver.

Flat or squamous epithelia: Formed by flat cells, with much less height than width and a flattened nucleus. It is one of the most external being part of the epidermis and generating some inconveniences when penetrating with needles to perform blood extractions when you have certain characteristics of hardness.

Determine which of the following sets of data satisfy the first law of thermodynamics? (Recall that E = total energy = U + KE +

qwelly [4]

Answer:

Only option a and b follows the first law of thermodynamics.

Explanation:

As we know that the first law of thermodynamics tells the conservation of energy,that is why it is also called quantitative law.

From the first law of thermodynamics

Q = ΔE + W

Given that

W= 50 KJ,Q= 170KJ ,ΔE=120 KJ

Yes this follows the first law of thermodynamics.

Given that

W= 100 Btu,Q= -110 Btu ,ΔE= -210 Btu

This also satisfy the first law of thermodynamics.

Given that

W= 250 KJ,Q= -110 KJ ,ΔE=-100 KJ

Yes this does not follow the first law of thermodynamics.

Given that

$W= 44 \frac{KPa}{m^3},Q= -84\frac{KPa}{m^3} ,\Delta E=40 \frac{KPa}{m^3}$

Yes this does not follow the first law of thermodynamics.

So only option a and b follows the first law of thermodynamics.
