E G R U Merits Teacher Comment: Having read through the ‘Design for manufacture’ list the keywords that you think are the most important terms or words Scales of Production Mass One off Continuous Batch Discuss in groups what the following words mean.

E G R U Merits Teacher Comment: How could a factory double out put on this sheet? In pairs discuss how the manufacturer could increase the production.

E G R U Merits Teacher Comment: Brief: You are going to design a flower holder for a market, the flower holder will be made from sheet MDF and will be bought flat packed. Problem: A company has bought a massive stock from a factory that has gone into liquidation, within this stock they have an abundance of test tubes. They now want to make money from these test tubes and require designs to make them into flower holders.

E G R U Merits Teacher Comment: Look through books, magazines, catalogues, etc to find pictures of flowers, flower and candle holders. Look on the internet too if possible. Record your findings below, say why you chose each picture and what elements you like and how you might use this in your designs. Investigate Homework sheet You need to show that you can obtain information from a variety of sources.

E G R U Merits Teacher Comment: Ideas Using the inspiration image sheets come up with shapes that you could use in your designs. Use card modelling to help you think through the viability of the designs.

E G R U Merits Teacher Comment: Complete a series of dimension drawings to show the limitations of the test tube. Draw it full size and orthographically. Clearly and carefully add the dimensions. Investigate When investigating I obtain data that will be useful when developing my design.

Using the orthographic information, use this page to come up with a range of different designs that incorporate your inspiration sheet shapes that could hold the test tube. Stick a picture of your cardboard model on here. E G R U Merits Teacher Comment: Ideas

E G R U Merits Teacher Comment: Mechanical properties of materials Compressive strength is the ability to withstand a pushing force which tries to crush or shorten. Tensile strength is the ability to resist stretching or pull forces. It is essential property of all cables, chains and ropes. Malleability refers to the extent to which a material can be permanently deformed in all directions under compression. Torsional strength is the ability to withstand twisting forces under torsion or torque. Bending strength is the ability to withstand the forces that attempt to bend a piece of material. Shear strength is the ability to resist strong sliding forces acting opposite to each other. Hardness is the ability to resist abrasive wear and indentation or deformation. Toughness is the ability of a material to withstand sudden shocks or blows. Brittleness is the tendency to show little or no strain before fracture.

E G R U Merits Teacher Comment: Mechanical properties of materials What forces are acting here? Discuss in your groups and label.

E G R U Merits Teacher Comment: Evaluation Think of 7 questions to ask 7 different people and draw a table to put the results into. Try and ask questions that need a yes/no answer, and one question needs to ask for improvements. Now in 5 sentences what did your survey show you?
