Consider a beam ABCD as depicted in the figure below. The lengths of the parts AB, BC and CD are $L_1 = 3L$, $L_2 = 3L$ and $L$, respectively. The beam has a fixed support at A. The part AB is loaded by a constant distributed lateral force of $q_0 = 2F/L$. At point D a downward concentrated force $F$ and at point C a counterclockwise external moment $M = 2FL$ is applied. The modulus of elasticity is $E$ and the second moment of area is $I$. Note: the positive direction of the coordinate $x$ and the vertical displacement $v$ have been indicated in the figure below. Find the vertical displacement $v$ at point D, expressed in $F$, $L$, $E$ and $I$. For this, the principle of superposition will be used, i.e. the displacement is a result of the sum of the individual contribution of the three load cases I: distributed lateral force $q_0$. II: concentrated force $F$ and III: moment $M$. $q_0$ M $L_1$ $L_2$ $L$ A B C D Contribution of load case I to the vertical displacement $v$ at point D = Contribution of load case II to the vertical displacement $v$ at point D = Contribution of load case III to the vertical displacement $v$ at point D = F x
Texts: Per the Wheatcraft paper cited on the Learning Materials page, "An interface is a boundary where, or across which, two or more parts interact." Find an example of such an interface in a web-facing application. An example here might be the college's class registration pages, where a system defining classroom capacity might need to interface with students' academic records. Another example might be an auto parts website's product pages that need to interact with an inventory tracking system. Consider the implications that arise when an Amazon shopping cart has to interact with a payment system or a shipping system. Countless other possibilities exist. Write a simple example of an interface control document for the interface you've identified. Use the templates in the ancillary resources section of the Learning Materials page as guides. The Process to Write Interface Requirements section that begins on page 3 of the Wheatcraft paper provides another solid guide. Your interface control document does not need to be anywhere near as robust as the examples; a couple of pages should suffice. Include only the sections that are relevant and feel free to include illustrations if they are helpful.

(b) Draw a sketch for each velocity case above and each acceleration case above. (c) Determine the radius of curvature of the parabola at the points where $\theta = 0$ and where $\theta = 90^\circ$. (d) Write a short comment about something useful that you observe about your result. (e) Assume that the system shown is in a vertical plane. Suppose that the pin as has mass $m$ and the spring has constant $k$ and relaxed length equal to 4$b$. Determine the normal force between the pin and the track at the point where $\theta = 90^\circ$. (f) Write a short comment about something useful that you observe about your result. PROBLEM 11.165. As rod OA rotates, pin P moves along the parabola BCD. Knowing that the equation of this parabola is $r = 2b(1+cos\theta)$ and that $\theta = \omega t$, determine the velocity and acceleration of P when (a) $\theta = 0$, (b) $\theta = 90^\circ$.
