Independent variable: length of ruler projection dependent variable: depression of ruler graph of depression was plotted against ruler projection (l^3) this formula is used: d = (4mgl^3) / e bw^3 how can i use the show more i did an experiment at school to measure the young's modulus of a metre ruler.

Of metre ruler is not exceeded (it should spring back to its starting position) figure 1 plot a graph of d against l3 for a range of values of d and l, and obtain the best straight line fit if we assume the relation where and e is the young’s modulus for the wooden ruler, obtain a value for e. A level physics : young's modulus i need help designing an experiment for determining young's modulus of a meter rule it came out in a level physics paper 5 we were given a diagram showing a ruler clamped to a fixed point the opposite end of the ruler is loaded with a mass m and the time period for 10 oscillations is to be noted. Finding young’s modulus of wooden metre ruler introduction: young’s modulus is also known as tensile modulus it is the measure of elasticity and it is a very important characteristic of a material the formula of young’s modulus is stress by strain.

How accurately a measurement of the young's modulus can be made depends upon the accuracy to which mg, mg, y, l, b and d can be measured a classroom ruler might only measure y, b and d to the nearest millimeter.

Instead show more i need help designing an experiment for determining young's modulus of a meter rule it came out in a level physics paper 5 we were given a diagram showing a ruler clamped to a fixed point the opposite end of the ruler is loaded with a mass m and the time period for 10 oscillations is to be noted. Homework help: simple question about young's modulus nov 28, 2012 #1 lionely i did a practical worked the gradient and calculated e, of a wooden metre rule what i want is a value to compare my value with, i got 5 n/m 2 so 5n will bend the ruler 1m seems likely right lionely, nov 28, 2012 physorg. You can see from the discussion of accuracy in the article that these can get very big (as much as 56% it says) so you only need the right order of magnitude conclude: youngs modulus for a wooded meter-rule was experimentally determined to be _____gpa.

- The young¶s modulus e of wood of the meter rule is given by where m = mass of the slotted mass, d = deflection of the end of the ruler s = gradient of graph d against m hypothesis .
- What is the young's modulus of a metre ruler i did an experiment at school to measure the young's modulus of a metre ruler independent variable: length of ruler projection dependent variable: depression of ruler.

Finding young’s modulus of wooden metre ruler introduction: young’s modulus is also known as tensile modulus it is the measure of elasticity and it is a very important characteristic of a material.
