    Investigating Wood Expansion/Contraction with Strain Gauges

    Lol just make sure you don't burn your wood into ashes.. We aren't going to be doing this experiment for our actual thing.. According to my teacher

    Thats what some people said.. But it sounds stupid.. I'm not sure about it.. But yeah the cicuit you use should amplify the small resistance into a voltmeter reading which can then be used to calculate resistance by R=V/I

    I'm not sure if that would really work tbh.. Don't think it would be balanced.. But then again I'm not sure

    You heat the wood up first.. Remove it from the lab oven, obviously wearing oven gloves (can be talked about in the safety precautions) then connect the wood into your circuit and measure the readings you need.. You need a range of temperature readings.. Read the question again: Design an...

    I'm doing the same thing.. Stuck on the same issue about resistance.. and also temperature.. How can you measure the temperature of the wood..? I am going to heat my wood by using a lab oven
