Quiz 1. A normal water battle is shown below. Design a water bottle for kids. Age group (4 to 6 years). So that they are always happy to use it. Mention the special features you would incorporate in it to achieve this. Give a simple sketch of your design. 2. In certain situations, users require extra length for their mobile charger cable. But offering extra cable length becomes an issue while normal usage. Develop a design to effectively solve this problem. Also give objectives and constraints for your problem. (Hint: Adjustable cable length, Avoid entanglement of cable) 3. After every academic year, our institution producing a large quantity of paper wastes even after too many preventive measures. How we can recycle this effectively. (Hint: Suggest waste recycling methods, possible products from this method). 4. Disassemble the bookshelf in Fig re D . Use the materials to make another useful product. Show that the wastage of the material is minimal. - Stainless steel water bottle for kids. - The package contains one piece of a bottle (500 me). - It can be used as a flask. It helps in keeping drinks hot or cold for 24 hours. - It has an easy-open cap and wide mouth for easy filling and cleaning of the bottle. - Cap come with easy opening and sealing. - 100% rust free matesial for safety and hygienic. - The themes like a superhero or other cartoon characters makes it more attractive. I 1111198 I Y.g.MG 2 The objective is extra length of wire and entanglement free The main area of concern is the entanglement caused when the full cable length is not in usage that is the cable is not fully stretched to its limit. The best alternative to get a best result would be casing it inside a circular structure, one such object we use in our day to day life is a measuring tape where we easily extend and reduce the length of the tape by rotating a handle bar over it. We will have to fix the USB port side that is the adapter connecting point of the cable at a particular length and mount the rest of the length on the extension wheel which will help to use the appropriate length keeping the cable free of entanglement.

Also the cost less than 100 SR And weight not to exceed 1 kg And 10 years lifetime 3 Paper recycling method Paper is taken from the bin and deposited in a large recycling container along with paper from other recycling bins. The paper is taken to a recycling plant where it is separated into types and grades. The separated paper is then washed with soapy water to remove inks, plastic film, staples and glue. The paper is put into a large holder where it is mixed with water to create ‘slurry’. By adding different materials to the slurry, different paper products can be created, such as cardboard, newsprints or office paper. The slurry is spread using large rollers into large thin sheets. The paper is left to dry, and then it is rolled up ready to be cut and sent back to the shops Recycling can be effective by taking the following measures, 1. Keep a separate recycling bin next to the trash can where paper is used heavily and don't mix this waste with others. 2. Know the paper types keep them separately and forward to the recycling center separately. 3. Always use both sides of the paper before recycling it. 4. Reuse files, folders, and envelopes by changing the names over them. 5.Use the electronic medium for communicating information to the students and staff on campus instead of using a notice board. 6. Always hand over the used paper to the Post-consumer of paper who use the used paper for their need 7. Sort your email and documents into electronic folders instead of printing them From the various methods of the paper recycling different products are obtained as given below 1. Papers for office: 2. Toilet papers and tissue papers 3. Towel papers and napkins 4. Greeting and invitation cards 5. Cardboards 6. Magazines and newspapers The Advantages of Recycling Paper Preserving Resources Reduces Greenhouse Gases Saves Energy and Water Saves Space in Landfills 4 The bookshelf material if considered wooden, then useful products one can make out of it with minimal wastage of material are as following 1) Two plates present inside the rectangular box can be used for making the different things below like a) vegetable cutting/chopping plate for kitchen b) Wooden tray to serve guests. 2) While the outside rectangular box without any material wastage can be used as it is for a) For planting different varieties of plants b) For storing toys of children c) The rectangular box can be even converted to pets house for dogs or cats.
