To calculate the measured stress given the provided data, we will use the relationship between strain and stress in the context of the material's properties.

First, let's define the given variables:

• $\text{mV/V} = 0.5$
• $F = 50 \, \text{N}$ (Force)
• $\nu = 0.33$ (Poisson's ratio)
• $E = 69000 \, \text{MPa}$ (Young's modulus)
• $\text{Strain factor} = 2.050580998$

Measured stress, $\sigma$, can be calculated using Hooke's Law, which relates stress and strain through Young's modulus:

$\sigma = E \cdot \epsilon$

where $\epsilon$ is the strain.

The strain $\epsilon$ is given by the product of the strain factor and the mV/V value:

$\epsilon = \text{Strain factor} \times \frac{\text{mV}}{\text{V}}$

Substituting the values:

$\epsilon = 2.050580998 \times 0.5 = 1.025290499$

Now, using Hooke's Law to find the stress:

$\sigma = E \cdot \epsilon$

Convert $E$ from MPa to Pa (since 1 MPa = $10^6$ Pa):

$E = 69000 \times 10^6 \, \text{Pa}$

Then:

$\sigma = 69000 \times 10^6 \, \text{Pa} \times 1.025290499$

$\sigma \approx 70745134.431 \, \text{Pa}$

Thus, the measured stress is approximately $70.75 \, \text{MPa}$ (since $1 \, \text{Pa} = 10^{-6} \, \text{MPa}$).
