My graphs showed me a good set of results. 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: When the distance between the supports increased the sag also increased, but not in a proportional way. As you can see, my graph produced a curve and this was due to the bonds in the wooden rule reaching it elastic limit.

Once the weights were added, the level of deflection appeared to be different. 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.Deer, Wooden Height Growth Chart Ruler for Kids, Roe Doe, Nursery Forest Woodland Decor, Boho Farmhouse, Kids Gifts for Easter Christening

Wooden puzzle height chart child-baby wall personalized CHAT - Laser cut-Laser cut-Decoration-Size scale-Ruler-Measure size 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.Jungle Elephant Ruler Growth Height Chart, Personalized Kids Safari Nursery Decor, Modern Boho Rustic Style, Height Chart Measurement Ruler When external forces act upon a beam in a direction away from its ends or a direct pull, the stress is a tensile stress. The strain is an increasing. When a forces act toward the ends or a direct push, the stress is a compressive stress. The strain is a decreasing.

After ten weights are applies and the level of deflection are taken I will change the length variable by moving the tables so that 0.1 meters of the rule will be covered and then redo the measurements. I shall decrease the length of the ruler by 0.05 meters each time about five times.

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. Wood Height Chart Growth Chart Personalized Growth Chart Wooden Nursery Decor Family Growth Chart Baby Growth Chart Stiffness is the property by means of which a body acted upon by external forces tends to retain its natural size and shape, or resists deformation. Thus a material that is difficult to bend or otherwise deform is stiff. Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. One object of such investigation is to find unit values for strength and stiffness, etc. These, because of the complex structure of the materials, cannot have a constant value which will be exactly repeated in each test, even though no error be made. The most that can be accomplished is to find average values. On account of the great variability in strength of different specimens even from the same material and appearing to be alike, it is important to eliminate as far as possible all extraneous factors liable to influence the results of the tests.

This wooden ruler will be a fantastic addition to your sewing kit, and will even prove useful for other general tasks. You'll be able to ensure absolute precision with this handy measuring tool!I think my results were quite reliable. There were a quite a few problems which affected my results. The fact that we couldn't stop the weights hanging on the piece of string swaying side to side hindered our results. The main problem was Hooke's law. As the force of the weights increased the ruler begins to stretch the atoms in that wood move apart in a regular way so that the extension of the ruler doubles each time that the force doubles. As the wire continues to stretch, the atoms in the wood move even further apart. As soon as the elastic limit is reached, the layers of the atoms slide over one another, and the length of the ruler increases rapidly. Once the force is removed from the wire, the wire does not return to its original position. This affected my results and meant that I got curved graphs instead of straight line graphs. wooden rulers, 1 with 5 holes that shall be made big enough so that the nail can fit comfortably through. The holes will be drilled at the 0.05, 0.10, 0.15, 0.20 and 0.25 meter points. As the weight increased, the bonds expand. When the length gets to 0.75M some of the bonds have started to reach there elastic limit. When bonds reach their elastic limit and the weight is taken of they do not return to their original size, making the weight being added have more effect on the structure.
