1 00:00:02,609 --> 00:00:20,920 Today we are going to summarize the main ideas about what technology is and the project method. 2 00:00:20,920 --> 00:00:29,129 So, to this question, what is technology? 3 00:00:29,129 --> 00:00:34,130 And it's very difficult to answer this question because it's not very easy. 4 00:00:34,130 --> 00:00:58,929 and technology is to make our life easier in order to reach this main 5 00:00:58,929 --> 00:01:11,950 target. It usually creates objects. Objects which are very useful but they 6 00:01:11,950 --> 00:01:19,829 are in the natural and it could be the main characteristic of technology. 7 00:01:19,829 --> 00:01:39,200 this process which consists in the creation of new objects, of tools. To do this, technology 8 00:01:39,200 --> 00:01:54,420 usually make things by a method. We know, we call the project method and it's 9 00:01:54,420 --> 00:02:01,760 more important in technology. Our activity is based on this, on making 10 00:02:01,760 --> 00:02:12,550 different kind of projects. You should follow three steps, which are design, 11 00:02:14,150 --> 00:02:21,750 production, what you have designed, and finally evaluate 12 00:02:23,990 --> 00:02:35,090 if you have reached the objectives or not. The first of these steps 13 00:02:35,090 --> 00:02:48,590 is not very simple because firstly someone proposed you a new project, gives you some 14 00:02:48,590 --> 00:03:06,949 information about what she or he needs to ease his or her life. 15 00:03:06,949 --> 00:03:24,229 so before doing anything you should share information because our technological development 16 00:03:24,229 --> 00:03:39,830 is very big so it is very possible that other people have answered the 17 00:03:39,830 --> 00:03:51,050 question you have to answer. Apart from this our technological development is 18 00:03:51,050 --> 00:04:04,069 very complex and if you if you want to make something is better to improve or 19 00:04:04,069 --> 00:04:17,790 is better and have something to help you at the beginning so in any case you need 20 00:04:17,790 --> 00:04:28,250 to a search information to create and to answer the question you have to 21 00:04:28,250 --> 00:04:39,769 answer. After that you should create ideas and to do this you can look at 22 00:04:39,769 --> 00:04:52,350 natural or you can use different methods to create new ideas. 23 00:04:52,350 --> 00:05:06,250 When you have an idea you should evaluate in order to choose the better idea and to 24 00:05:06,250 --> 00:05:23,949 do this you you should evaluate if it can cover your needs or if it is 25 00:05:23,949 --> 00:05:33,910 simple or it is very complex and also it is cheap or it is expensive. All of 26 00:05:33,910 --> 00:05:44,670 these help you to choose the best idea. You have to express your ideas using obviously 27 00:05:44,670 --> 00:05:53,310 the technological rules for expressing ideas. And after that you have to develop, you have 28 00:05:53,310 --> 00:06:05,740 to do a good planification for this. The planification is a very important part of our design. 29 00:06:05,740 --> 00:06:16,740 Here you can see a very simple planification, a very typical planification for one of our projects. 30 00:06:16,740 --> 00:06:27,740 Well, in other words, it's not just for a project, it's more for one piece, but it's a project. 31 00:06:27,740 --> 00:06:34,300 and it's a it's it's very simple it's just a as you can see you know you have to 32 00:06:35,019 --> 00:06:44,060 um have you you you have to to do different tags you know in a in a typical order 33 00:06:44,060 --> 00:07:00,259 and for each stack you need materials, tools and time. And we can also put some money, 34 00:07:00,259 --> 00:07:16,759 I think this is easy enough at least at least now did this kind of documents can 35 00:07:16,759 --> 00:07:29,939 help you to make a good planification because it let you to know and time 36 00:07:30,259 --> 00:07:43,259 From it you can do a list of materials and a list of tools, so it helps you to make a good planification. 37 00:07:43,259 --> 00:07:53,180 It is important to express well your ideas. 38 00:07:53,180 --> 00:08:09,000 I think everybody draws, everybody can draw, but what is more difficult for you is expressing 39 00:08:09,000 --> 00:08:16,910 the ideas using the technological rules. 40 00:08:16,910 --> 00:08:28,750 The draws could be different, you can't draw something without any rule, and it is a draft. 41 00:08:28,750 --> 00:08:41,409 But if you follow a perspective and you put more details in your draft, it is a draft, 42 00:08:41,409 --> 00:08:44,190 now it is a sketch. 43 00:08:44,190 --> 00:09:00,269 And finally if you draw using materials and with a very good perspective and full of details 44 00:09:00,269 --> 00:09:04,549 is just a technical draw. 45 00:09:04,549 --> 00:09:12,259 For us and for our project a sketch is enough. 46 00:09:12,259 --> 00:09:25,279 you should do or you should follow the technical rules. You should draw using perspective, 47 00:09:25,279 --> 00:09:37,580 using what you usually call European system. This system, this kind of perspective, 48 00:09:37,580 --> 00:10:01,580 consists on expressing things using the perpendicular projections in the space. 49 00:10:01,580 --> 00:10:19,519 Obviously, space has six possible perpendicular projections, but you should just only use three 50 00:10:19,519 --> 00:10:30,860 of these, which are the front projection, the upper top and one of the side projection. 51 00:10:30,860 --> 00:10:46,639 These projections are called views and you should put the upper top projection behind 52 00:10:46,639 --> 00:10:57,559 the front projection and the left side projection on the right and the right side projection on the 53 00:10:57,559 --> 00:11:12,450 left and this is the way you have to express the different things. Apart from 54 00:11:12,450 --> 00:11:24,250 expressing the projection you also add the dimension of the objects. To do that 55 00:11:24,250 --> 00:11:34,850 you use lines. We usually call delimit lines. A delimit line usually has 56 00:11:34,850 --> 00:11:48,090 the delimiter auxiliary line, the delimiter line itself, 57 00:11:48,090 --> 00:11:56,090 which is ending in arrowhead and in the middle of the line you should put the 58 00:11:56,090 --> 00:12:08,220 value in millimeters without a millimeter symbol. It is very important 59 00:12:08,220 --> 00:12:16,139 give details for a project. So one project usually have more than one part 60 00:12:16,139 --> 00:12:33,639 So you have to do a catalyst, you have to describe each part of our project with the material in which you have to build this part. 61 00:12:33,639 --> 00:12:49,490 And sometimes it's important to express the way they have to join in the project. 62 00:12:49,490 --> 00:13:02,990 With all this information, we usually do a document, which people usually call project, but indeed it is a proposal. 63 00:13:02,990 --> 00:13:25,629 A typical proposal usually have a cover page, INGEX, memory, description memory, planification, material list, tool list, a budget, the sketches and the cut list. 64 00:13:25,629 --> 00:13:47,600 I think this is more important information for this part. Now we have to put all this in practice and it's your turn. I'll see you in the next class.
