Problem 13-70

The package has a weight of 5 lb and slides down the chute. When it reaches the curved portion AB, it is traveling at 8 ft>s (u = 0). If the chute is smooth, determine the speed of the package when it reaches the intermediate point C (u = 30) and when it reaches the horizontal plane (u = 45). Also, find the normal force on the package at C.

University of California Davis Prof: Alissa Shubb Intro to Public Speaking CMN 001 Process of Putting Together a Speech ● Invention ○ General Purpose ie. inform, persuade, entertain ○ Topic - must research (research will help to narrowly focus) ○ Specific Purpose (Central Idea) *note: if a speaker obfuscates their intention (general purpose) -ie. they say they are going to inform, but instead they persuade- then they will lose the audience’s trust; and therefore, diminish their good moral character and in turn their credibility ● Arrangement ○ Intro - Tell the audience what you will say ○ Body- Say it ○ Conclusion- remind your audience about what you said ● Style ○ Language Style ■ Clarity ■ Correctness- say the correct terms with the correct pronunciation ■ Vivid - paint a picture in the audience’s mind ■ Appropriate ● To self - make sure you sound like yourself/ natural ● To the audience- make sure you use words the audience will understand ● Situation and topic- make sure you use words that are appropriate for the situation and for your topic ○ Presentation Aids ■ Enhance clarity ■ Service retention ■ Add interest ● Memory ○ Remember what you are going to say- do not memorize how you will say it ■ Memorization can lead to a broken chain in your memory that will cause you to forget everything else ○ Memorizing can be done for your intro and conclusion to have more control ■ Memorize with slight deviations so that you can avoid broken memory chains ● Delivery ○ Practice the way you are going to be presenting the speech ■ Practice with your notes & visual aids ○ Use silence without revealing what’s going on in your mind to get your thoughts together Structure of Opening and Closing Intro Conclusion 10-20% ********Keep it short******** Get the audience’s attention Signal end (sign post)  Utilize the primacy effect- the very  ie. Say in conclusion, or now to first word you say should be conclude, rapping it up here… strong  Make it about the audience not yourself ****Must be related to topic, not too broad**** -do not inadvertently insult/annoy/offend your audience Reveal your topic Provide closure  Make it special  Repeat what your main points  Build ethos- connect yourself to were the topic  Reveal your bias Preview main points End with a dramatic statement ******Thesis Statement******* *Must match the topic and general  Clearly articulate what you are purpose!!* going to cover  Crescendo- “Ah” moment  Diminishing ending- “hmm” ending ie. Posing a rhetorical question  Circular ending- going back to the into and connecting to how you started the speech Structure of Specific Purpose (Body) METHODS  LENDS ITSELF TO: {Specific Purpose} Chronological Use of time Showing how something changed over time Spatial Use of area Showing differences Causal Use of cause & effect Explaining a phenomenon & its causes Topical Use of categories/ natural Breaking down topic to divisions/ subtopics constructing meaning
