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. The mechanical properties of materials are its fitness and ability to resist applied or external forces. By external force is meant any force outside of a given piece of material which tends to deform it in any manner.

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. 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.Friction between the hole and the nail as well as the table and the rule. Sometimes the rule swung diagonally and might have rubbed the table. Once the experiment was set up I started to take measurements. 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. I repeated this until 10 times 100 gram weights had been added. wooden growth chart rainbow, ruler height chart rustic vibe, solid wood decoration for a child room, vintage 1th birthday gift, 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~. Eventually a point will be reached where the recovery of the specimen is incomplete. This point is known as the ~elastic limit~, which may be defined as the limit beyond which it is impossible to carry the distortion of a body without producing a permanent alteration in shape. After this limit has been exceeded, the size and shape of the specimen after removal of the load will not be the same as before, and the difference or amount of change is known as the ~permanent set~. Once some weights were added the set up looked unstable and dangerous as the rule started to twist. This could have been because the clamps were no tightened at the same strength.

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. Stress is a distributed force and may be defined as the mutual action:When a forces act toward the ends or a direct push, the stress is a compressive stress. The strain is a decreasing.

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. I could have tested shorter lengths, this would have allowed me to really see if the pendulum and sag has any similarities when the length was constant. 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.Wooden puzzle height chart child-baby wall personalized OWLS - Laser cut-Laser cut-Decoration-Size scale-Ruler-Measure size 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.

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! custom personalized wooden growth chart wooden growth ruler wood growth chart engraved name engraved numbers engraved lines 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. Deer, Wooden Height Growth Chart Ruler for Kids, Roe Doe, Nursery Forest Woodland Decor, Boho Farmhouse, Kids Gifts for Easter Christening I also found that the rule was slipping from the clamp when the weights were applied. This also makes the rule much harder to bend than where the pieces were held together. This results in the stiffness of the material to be increased.

The bonds in the wooden rule started to reach their elastic limit at about 0.75m, the bonds in the metal rule some of the bonds started to there elastic limit at about 0.70M. The sag at the point when the elastic limit was reached for the metal rule was about 0.01m, whereas the sag point when the elastic limit was reached for the wooden rule was about 0.0015. This shows that the wooden rule has a lower elastic limit compared to the metal one.
