After the maths of last week's question, here is\u00a0something to make your brain\u00a0work in a slightly different way!<\/p>\n
UPDATE: Its about real world design and the implications of inaccuracies in construction.<\/p>\n
A person weighing 600N sits on a three-legged stool. \u00a0For what basic force should each leg be designed? There is no catch to this problem - the stool is to be symmetrical, the person sits in the center of the seat. \u00a0The answer is of course \u00a0200N<\/p>\n
The same person now sits on a square \u00a0stool with four legs, one at each corner and again the stool and the loading are symmetrical. For what force should each leg of the stool be designed?<\/p>\n
You can assume the floor is flat and rigid!\u00a0Once you have decided how much load each leg should be designed for, please answer the question below.<\/p>\n
Which type of stool uses the least \u00a0amount of material in the design of each leg?<\/p>\n
Voting \u00a0is now closed!<\/span><\/strong><\/p>\n Well done to the 62 people that entered the quiz. If you consider that the length of each leg maybe very slightly different, then the 3 legged stool is by far the best design requiring 50% of the material in the legs than the 4 legged stool.<\/span><\/p>\n If you didn\u2019t get this answer please read through the <\/a>SOLUTION<\/a>.<\/span><\/p>\n Mark<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" After the maths of last week's question, here is\u00a0something to make your brain\u00a0work in a slightly different way!
