Product Information

For my first rough experiment I experimented sag. I set up the experiment which is shown under the heading ‘rough trials apparatus 1’. I first put two stands on a table and attached the clamps to the ruler so that 0.05 meters of the rule at both ends were covered. I then put a stand which was holding another rule attached by a clamp in the middle of the horizontal rule; this is to measure the amount of deflection. Then I put some string around the middle of the horizontal rule, this is to allow me to attach the weights. I will not move when I am placing the weights on the rule and recording my results. I shall do this by keeping the weights near. Based on my graph where only 0.98N were attached to the centre of the rule, as the length increased the sag also increased and it produced a straight line which proved that the reason it curved when more weights were added was due to its elastic limit.

This was probably because I had to get up to get the weights and the position of myself and the vertical rule change. This could result in inaccurate results.

This will be difficult to fix as it is down to human error. So the best way to resolve this will be to pay as mush attention to the experiment in action as possible.Easy-To-Read Markings: This straight-edge ruler features sharply delineated numerals and graduations designed to ensure easy readability The second experiment I will do is the compound pendulum, with this I will be able to work out the time period, and see if there is a relationship between the sag and time period.

Birthday Gift Growth Chart for Kids, Wooden Growth Chart, Wooden Nursery Decor, Baby Height Chart, Baby Personalized Growth Chart Ruler Wooden rulers are ideal for use at home or in schools, as the wood has a smooth surface, is clear to read and won't split.The length of the rule may not have been exactly correct, as all I did was lay it on the table therefore it could have moved when I was adding weights or not been place accurately.

Knowledge of these properties is obtained through experimentation either in the employment of the wood in practice or by means of special testing apparatus in the laboratory. Owing to the wide range of variation in meter rulers it is necessary that a great number of tests are made and that so far as possible all disturbing factors be eliminated. For comparison of different kinds or materials a standard method of testing is necessary and the values must be expressed in some defined units. For these reasons laboratory experiments if properly conducted have many advantages over any other method. When the distance between the supports increased the sag also increased, but not in a proportional way, just like in the wood. The reason it curved was just like the reason the wood curved, this was because the bonds were reaching its elastic limit.

The distance the rule was moved to be ready for the swing was 0.2 meters. This could have not been accurate for each experiment as I had moved and so the position may seem the same but in fact be different.

Useful sewing ruler It is difficult to find a 1 metre sewing ruler at a reasonable price so this fits the bill. Nice to have metal ends so the wood can't split but the metal conceals the first centimetre and a half and the last 1+1/2 . If you want to measure a metre of material then mark a small seam allowance at the same time it is difficult to work out where to mark. The other side of the ruler's markings ends at 36 inches too so it's impossible to compare cm to ins over 36 inches. Size of the displacement: This was 0.2m. Each measurement has an absolute error of ±0.5 centimetre as each measurement is given to the nearest centimetre.

These stresses may act together, producing compound stresses, as in flexure. When a bow is bent there is a compression of the fibres on the inner or concave side and an elongation of the fibres on the outer or convex side. I measured the sag with another meter rule and it was hard to get accurate data from and it showed millimetres but when the length of the horizontal rule became shorter it sometimes took several weights to read 1 millimetre. ruler for boys,1st class ruler,custom ruler,engraved ruler,personalised Wood Ruler,centimeter ruler,School ruler,math ruler,initial on ruler My graph had a straight line of best fit which represented the results gained. The graph had a straight line travelling diagonally upwards towards the right, this is because as the force of the weight increased the depression of the ruler also increased, and this is due to Hooke’s law. I drew a curved line of best fit for when the force used way 9.8N; this was because of elastic limit which is explained in analysis. There were some irregular results gained from some of my graph, but they were not seriously out of line from the best fit. These could have occurred from a number of errors:
