| ====== To Do ====== | {{:course_planning:projects:boar_tiger_defense2.png?|}} |
| |
| ==== 09/07/2014 ==== | You have been sent to a remote outpost in Icy Cape, Alaska. While at the outpost, strange things start happening and you are being constantly attacked by an animal that seems to be a weird tiger/boar boar combination. Your base is located at the shore of a large frozen lake across from which is the boar tiger breeding ground. The outpost was formerly a foundry for metal working; several large rectangular blocks (5 $\mathrm{m}$ wide; 1 $\mathrm{m}$ high; 1 $\mathrm{m}$ deep) of steel rest on the frozen lake. The steel made at this foundry has a density of 7850 $\mathrm{kg/m^3}$. |
| |
| * <del>Start to do list</del> | Roving in packs of precisely 101, boar tiger hide cannot be penetrated by conventional weaponry (i.e., bullets and knives). But there are some abandoned cannons you could use to defend the outpost. The cannons were engineered to fire .3 $\mathrm{m}$ diameter cannonballs at a speed of 1600 $\mathrm{m/s}$. These cannonballs are made of clay with a very thin steel shell ($m = 200 kg$). These were found to be laegely ineffective against the packs of boar tigers. However, a member of your team observed that boar tigers were afraid of objects with swinging or sweeping motions. |

| * Write Examples | They asked you to design a defense system that can defend against packs of boar tigers using the cannons (already in place) and the large, rectangular steel blocks. In his mind, it could be possible to have the steel blocks slide and rotate along the ice, sweeping up the attacking boar tigers along the way. |

| * We need to start developing assessments (exams) | To determine if such a defense mechanism is feasible, <wrap caution>Dr. You need to determine how the steel block will move and with what speed it could be expected to strike boar tigers. |
| * <del>Add clicker questions/notes for forces</del> | |
| * We need 4 new videos | |
| * [[temp:prelec:momentum|1 pre lecture video - define momentum and discuss momentum principle]] <wrap todo> (Put in graph bit) </wrap> | |
| * [[temp:prelec:CF-g|1 pre lecture video - talk about the concept of gravitational force and how it relates to projectile motion - 3dimensions]] | |

| * [[temp:prelec:springs|1 pre lecture video - discuss difference between systems undergoing non constant and constant forces]] | |
| * [[temp:prelec:newtoniangravitation|1 pre lecture video - break down newtonian gravitation especially its reciprocal nature.]] | |
| * 1 example video - applying the momentum principle | |
| * 1 example video - demonstrating the iterative prediction of motion | |
| | |
| * Fan Cart Videos to keep: | |
| * 1 - const v (sdjsaxLfevQ) | |
| * 2 - const F (MAa7sYKa5GA) | |
| * 8 - F opp v to start (3Bi0uvqBL08) | |
| * 12 - const v; with accelerometer (LxxwPZ5Ocis) | |
| * 14 - const F; with accelerometer (HSZV2vBALtY) | |
| * 19 - F pop v to start; with accelerometer (-b03kUELJQc) | |

| | |
| * For which problems, should we work the examples? Or should we generate new worked examples? Here's a sample. The audio is really low for some reason (and it's only 360p), but it uses the iPad, so it's quick. I can do more testing of the setup if we need to. | |

| | |
| * Here's a better version, which I exported in a different way. I can record and export them after a higher res, so that YouTube will recognize them as 720p. The audio still sucks, but I'm not sure why. | |
