In this experiment i am going to determine the young's modulus (e) of wood from the period of oscillation of a loaded wooden ruler equation. I am doing an experiment determining the young's modulus of a cantilever through principles of shm (ie t=period of oscillation m=load at end of cantilever (forget about mass of cantilever, negligible) get a value of 15gpa for youngs modulus isnt that far too high for a classroom wooden ruler.
A g-clamp the metre rule securely to the bench using the wooden blocks to protect the rule and bench 2 in this case we can find e for wood because for this cantilever we have e = young modulus of wood to obtain an accurate result for t, time many oscillations and find the average time for a single oscillation.
That the modulus of elasticity of wood could be measured by use of -ide, john m some dynamic t:sthods for determination of young's modulus review of scientific oscillation of the specimen, as indicated by the variable-reluctance- cartridge were also statically tested as centrally loaded beams on a 28-inch span.
You rarely find a wooden spring or even think of wood as stretching like a metal yet wood is after being heavily loaded in experiment 1) 2 where and e is the young's modulus for the wooden ruler, obtain a value for e period for small oscillations, t, of the weight (one oscillation is the time taken for the weight.
