Under static conditions, a 2000 kg car's suspension springs will deflect by 0.02 m. Assuming damping is minimal, determine the car's natural frequency in the vertical direction.

Refer to the image below by M.C. Escher. The piece is called Development I and was completed in 1937. Describe the center of rotation.

In this problem fill in the blank.

If $|2-x|=15$, then $x=$_______.

Choose the best response from the available range of options: The two-plane balancing is also known as: a. static balancing b. dynamic balancing c. proper balancing

Fill in the blank: $\int x \cos x d x$=-?-.

Knowing that a couple of magnitude $15 \mathrm{~N} . \mathrm{m}$ is required to start the vertical shaft rotating, determine the coefficient of static friction between the annular surfaces of contact.

A three-phase load impedance consists of a balanced wye in parallel with a balanced delta. What is the equivalent wye load and what is the equivalent delta load if the phase impedances of the wye and delta are $6+j 3 \Omega$ and $15+j 10 \Omega$, respectively?

Think about the development of aerotolerance categories in FTB. Where might you anticipate seeing a strict aerobe grow?

For the following exercise,

Find and graph two periods of the periodic function with the given stretching factor, $|A|$, period, and phase shift.

A tangent curve, $A=1$, period of $\frac{\pi}{3} ;$ and phase shift

$$(h, k)=\left(\frac{\pi}{4}, 2\right)$$

Fill in the blank: $\lim _{x \rightarrow 5} f(x)=$-?-

The delta function well supports a single bound state. Calculate the geometric phase change when $\alpha$ gradually increases from $\alpha_1,$ to $\alpha_2.$ If the increase occurs at a constant rate $(d\alpha /dt = c),$ what is the dynamic phase change for this process?

Explain why a wheel rolling on a flat horizontal surface can- not be slowed down by static friction. Assuming no slipping, what does slow the wheel down?

Reconsider Exercise earlier for the case of a manufacturing error introducing a second pole at $10^4 \mathrm{~Hz}$. What is now the frequency for which $|A \beta|=1$ ? What is the corresponding phase margin? For what values of $\beta$ is the phase margin $45^{\circ}$ or more?
