Bone has a Young’s modulus of $18 \times 10 ^ { 9 }$ Pa. Under compression, it can withstand a stress of about $160 \times 10 ^ { 6 }$ Pa before breaking. Assume that a femur (thigh bone) is 0.50 m long, and calculate the amount of compression this bone can withstand before breaking.

Find the center and radius of the circle and graph it.

$$x ^ { 2 } + y ^ { 2 } = 6$$

(a) Prove that if $\left\{\mathbf{v}_{1}, \mathbf{v}_{2}, \mathbf{v}_{3}\right\}$ is a basis for $R^{3}$, then so is $\left\{\mathbf{u}_{1}, \mathbf{u}_{2}, \mathbf{u}_{3}\right\}$, where $\mathbf{u}_{1}=\mathbf{v}_{1}, \quad \mathbf{u}_{2}=\mathbf{v}_{1}+\mathbf{v}_{2}, \quad \mathbf{u}_{3}=\mathbf{v}_{1}+\mathbf{v}_{2}+\mathbf{v}_{3}$ (b) State a generalization of the result in part (a).

Use Laplace transforms to solve the initial-value problem.

$$y^{\prime}-3 y=h(t), \text { where } h(t)=\left\{\begin{array}{ll}{10 \sin t,} & {0<t<2 \pi} \\ {0,} & {t>2 \pi}\end{array}\right.$$

$$y(0)=0$$
