The zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.

<h3>How would you identify zero-force members in truss?</h3>

You would definitely identify zero-force members in a truss by the fact that a joint has only two non-collinear members and there is no external load or support reaction at that joint, then those two members are zero-force members.

Zero-force members in a truss are the structural members that significantly support no loading but aid in the stability of the truss.

Therefore, the zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.

alexandr402 [8]

Explanation:

You can use Hollomon's equation to estimate this.

Y_f is the flow stress.

K is the strenght coefficient or constant.

e is the strain

n is the strain hardening exponent.

You should be able to solve for e given the data in the problem statement.

Anastasy [175]

Answer: The organism is an amoeba belonging to the protist kingdom.

Explanation: The organism cannot be placed in the plantae kingdom because the organism does not contain a cell wall or chloroplasts. The organism also cannot be bacteria or Archaebacteria because it has a nucleus. The organism cannot belong to the fungi or animalia kingdom because it contains psedupodium.

solong [7]

The guy named Kirby didn't touch the power button on the projector. If he touched means the projector will work fine.

<u>Explanation</u>:

  • Kirby touched the gear on the projector. He should check the projector carefully before operating the projector. But he didn't check properly.
  • There was a blue rip in the projector. Kirby fails to notice the blue rip. Without minding that he has started the projector. So the tape and the projector is not working well.
  • He should fix the blue rip and he should press the start button in the projector. The mistake is he didn't do that. This is the thing that made the projector ripped.

Derive the expression ε=ln(1+e), where ε is the true strain and e is the engineering strain. Note that this expression is not va
Rudiy27

The formula for true strain after derivation from basic terms is; ε_t = In(1 + ε_e)

<h3>How to derive the expression for True Strain?</h3>

Formula for Engineering Stress is;

σ_e = Load/Area

Formula for true stress is;

σ_t = Force/Instantaneous Area

Formula for Engineering Strain is;

ε_e = ΔL/L₀

Formula for true strain is;

dε_t = dL/L

Total true strain is gotten from;

ε_t = ∫(dL/L) between boundaries of L_f and L_o

When we integrate between those boundaries, we have;

ε_t = In[(L₀ + ΔL)/L₀

⇒ ε_t = In[(1+ ΔL/L₀)

⇒ ε_t = In(1 + ε_e)
