Answer:

54.

Explanation:

6 (v) x 9 (m) = 54.

54 (m) / 6 (v) = 9 (d)

Suppose a vertebra is subjected to a shearing force of 420 N. Find the shear deformation in m, taking the vertebra to be a cylin

vazorg [7]

Answer:

$1.34103\times 10^{-7}\ m$

Explanation:

F = Shearing force = 420 N

$L_0$ = Initial length = 2.6 cm

d = Diameter = 3.6 cm

r = Radius = $\frac{d}{2}=\frac{3.6}{2}=1.8\ cm$

E = Young's modulus = $80\times 10^9\ N/m^2$

A = Area = $\pi r^2$

Change in length is given by

$\Delta L=\frac{FL_0}{AE}\\\Rightarrow \\\Rightarrow \Delta L=\frac{420\times 0.026}{\pi 0.018^2\times 80\times 10^9}\\\Rightarrow \Delta L=1.34103\times 10^{-7}\ m$

The shear deformation of the vertebra is $1.34103\times 10^{-7}\ m$

Un automovil de 900 kg toma una curva de radio de 40 m con una rapidez constante de 50 km/h. Cual es la fuerza neta necesaria pa

Llana [10]

Answer:

Fc = 4340,93 Newton

Explanation:

Dados los siguientes datos;

Masa = 900 kg

Velocidad, V = 50 km/h a metros por segundo = (50 * 1000)/(60 * 60) = 50000/3600 = 13,89 m/s

Radio, r = 40 m

Para encontrar la fuerza centrípeta;

Fc = mv² / r

Fc = (900 * 13,89²)/40

Fc = (900 * 192,93)/40

Fc = 173637/40

Fc = 4340,93 Newton
