The fact that we couldn't stop the weights hanging on the piece of string swaying side to side hindered our results. 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. 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. I recorded the height of the rule without any weights added, I then added 100 grams and took down the difference in the level of deflection.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. This should mean that the position in which I let go of the rule will be similar throughout the whole experiment. So the best way to resolve this will be to pay as mush attention to the experiment in action as possible.

Easy to use Usually use plastic flexible tape for measuring, but using this wooden ruler for craft products is a lot easier. If successively larger loads are applied to a body and then removed it will be found that at first the body completely regains its original form upon release from the stress--in other words, the body is ~elastic~. A ruler, also known as a rule, is a flat, straightedge measuring instrument with equally marked spacing etched or moulded along its length.Study of the mechanical properties of a material is concerned mostly with its behaviour in relation to stresses and strains, and the factors affecting this behaviour. I think the results I gained from this experiment were sufficient enough for me to come to a formal conclusion. 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.

I am very pleased with the results I gained because they had shown me a good trend/pattern which I could refer to. If the results of similar experiments on different materials of a meter rule are plotted to the same scales, comparison is easy. When external forces act upon a beam in a direction away from its ends or a direct pull, the stress is a tensile stress. 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. Where P = normal force, L = beam length, w = beam width, t = beam thickness, y = deflection at load point.

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. The greater the resistance a material offers to deformation the steeper the vertical axis will be the line. 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 . X2 on the graph is the point from the nail to the centre of the rule which is the length of the rule. They are prevalent is particular fields of study including geometry, printing, technical drawing, architecture, building and engineering.
