Question

un resorte de 10cm de longitud recibe una magnitud de fuerza que lo estira hasta medir 15cm ¿cual es la magnitud de la tension unitaria o deformacion lineal? Si me explican la fórmula estaría genial!

Answer 1

Answer: 0.5

Explanation:

The modulus of elasticity (called "alargamiento unitario" in spanish) $\epsilon$ of a spring is given by the following formula:

$\epsilon=\frac{\Delta L}{L}$

Where:

$L=10 cm$  is the original length of the spring

$\Delta L=L_{f}-L$  is the elongation of the spring, being $L_{f}=15 cm$ the length of the spring after a force is applied to it.

$\epsilon=\frac{L_{f}-L}{L}=\frac{15 cm - 10 cm}{10 cm}$

Then:

$\epsilon=0.5$
