Hi, I am just wondering for a given set of stress strain data pts how we calculate youngs modulus/modulus of elasticity. I know i can use mo of elas= engineering strain over stress - i.e gradient, it keeps giving me different values for each set of points. And i dont know if i should graph it or whatver becasue first - wahts the point i already have data, secondly, its a really small number ie 0.056732. I dont think it was designed to be plotted.

So which answer should i use to get modulus of elasticity, the first data set? or just even the average. by the way the material is something called wine wood.

Much thanks,
