A plastic dowel has a Young's Modulus of $1.50\times 10^{10}\mathrm{N}/{\mathrm{m}}^2$. Assume the dowel will break if more than $1.50\times 10^8\mathrm{N}/{\mathrm{m}}^2$ is exerted. (a) What is the maximum force (in $\mathrm{kN}$ ) that can be applied to the dowel assuming a diameter of $2.50\mathrm{cm}$ ? $\mathrm{kN}$ (b) If a force of this magnitude is applied compressively, by how much (in mm) does the $23.0\mathrm{cm}$ long dowel shorten? (Enter the magnitude.) $\mathrm{mm}$ A $1470?\mathrm{kg}$ automobile has a wheel base (the distance between the axles) of $2.90\mathrm{m}$. The automobile's center of mass is on the centerline at a point $1.05\mathrm{m}$ behind the front axle. Find the force exerted by the ground on each wheel. each front wheel $\mathrm{kN}$ each rear wheel $\mathrm{kN}$
