"Ultimate Tensile strength", is measured as the number of Kilogram of force needed to fracture a 'unit' of Area of the material.
If you choose to use the Units of Kg for the force , and the Unit of Square Cm for the area; then the answer will be in Kilogram per Square Centimetre. You will now realise that it is NOT practical to measure tensile strength of paper because paper is extremely thin and it is not possible to make a piece of paper with an area of 1cmX 1 cm. Paper is usually about one twentieth of a mm thick. However, it you cut a strip of paper exactly 1 cm wide, from a telephone book with the pages clamped very tightly together between 2 strips of wood, and the stack of strips were exactly 1 cm thick; then you would have an area of SOLID paper which would be 1 cm X 1 cm. Now hang weights on it until it breaks apart. The Tension you created on the 1 square cm would be your answer.
Different types and qualities of paper will give very different results. In the same way , different types of steel have very different Tensile Strengths. Talk to an Engineer and he will explain the different between 'Ultimate' tensile strength, and 'Safe Working' tensile strength. Steel is an Elastic substance just like rubber, but it Ultimately stops stretching and breaks when its Ultimate tensile strength is reached.
If you know the specific type you can look it up in a handbook or product data sheet. If you do not know it, you can test a specimen with specific cross sectional area by pulling on it with a tensile testing machine that has a calibrated load cell. When it fails you calculate the tensile strength by dividing the measured failure load by the known area.
Depends on what alloy you mean. If you are talking about pure Al (AISI1xxx), it is generally accepted to yield about 7-11Mpa. Another thing to consider is that Al does not have as pronounced yield as say Fe systems. The 0.2% offset stress is used in most calculations regarding Al yield stress and is calculated as follows: L = length of sample ->0.2%*L=0.2% offset strain. Plot this point on stress/strain graph and draw line from this point on the strain axis parallel to the elastic slope of the material until it reaches the data points. This intersection is the 0.2% offset stress point.
Yes, it is possible to calculate.
if the cast iron consists of carbon in its free state then it is called a grey cast iron mechanical properties of grey cast iron tensile strength - 270 - 400 N/mm2 Brinell hardness number - 207 - 320 Modulus of elasticity - 1*105 N/mm2 poisson's ratio - 0.23 modulus of rigidity - 0.350 * 105
To mobilise the compressive strength of the full thickness of the slab. For an explanation see below. Concrete tends to be stronger in compression than tension. If you can imagine a large flat slab of concrete that is much wider than it is thick (for example a slab to be used in the construction of the floor of an upper level of a house), it will be supported at the corners or edges. This allows the centre of the slab to deform vertically downwards (by a very small amount). This deformation due to it's own self weight generates stresses in the slab. You now need to imagine that there was a straight line drawn along the centre of the edge of the slab from one end to the other. When the slab deforms this line will become a curve or arch. This is in fact what the slab is doing - performing as an arch. This means that the lower portion of the slab (below the line will have stretched and be under tension and the upper portion of the slab will have been compressed. Now in this case the failure strength of the arch is being controlled by the tensile strength of the slab which is much lower than it's compressive strength. As such when the concrete is being formed, high tensile strength steel wires are connected to anchor points in the factory and they are stretched or placed under a tensile stress. The concrete is than poured into a mould around the steel wire and allowed to set (or cure). The concrete than adheres to the steel cable. Once the concrete has fully hardened the stell wires are cut from the anchor points and the steel wires attempt to return to their original size, This stress is transferred to the concrete as compression by friction due to the bond between the c able and concrete. Now when the concrete slab is used as a floor it begins to deform under it's own weight, however the pre-stressed steel wires already under tension act to pull the entire slab including the base back into a compressive stress state meaning that the whole of the slabs compressive strength is mobilised rather than just the upper half and this effectively acts to make the slab stronger. There are a number of differing methods of making steel reinforce pre-stressed concrete and for further information, please see the related link.
Tear strength is measured as the force required to tear a standard test piece. The standard test pieces are designed to produce weak points where a tear is initiated
That depends on the type and construction of the plywood. Usually the manufacturer can provide you with the engineering specs for the matieral including tensile strength and various breaking points.

Full points minus the stuff you missed.
A bar of uniform strength refers to a structural element (such as a beam or column) where the material properties (such as its cross-sectional area or material composition) remain constant along its length. This ensures that the bar can withstand loads and forces evenly distributed across its entire length without any weak points.
To calculate points on the PointsPlus system, you would need to consider the food's protein, carbohydrates, fat, and fiber content. The formula used to calculate points on PointsPlus takes these nutrients into account to assign a point value to a food item. You can find PointsPlus calculators online or use the Weight Watchers app to easily calculate points for different foods.
In a uniform electric field with the same strength at all points, the electric field lines are straight, parallel, and evenly spaced. This indicates that the electric field strength is constant.
Create a closed polyline form the points and use the AREA command to calculate the area and perimeter.
It depends on the player and how they want to train their strength pure. Most strength pures will only train two skills: Strength and Hit Points.
When you level up in perfect world, you get 5 attribute points. Press c, then chose out of the for skills: Dexterity, vitality, magic and strength which ones you want to distribute points to.

It depends on what you're trying to calculate a percentage for. On a homework, test, or other scholastic assignment it would be:Total Points Earned ÷ Total Points Possible.Example: 45 points earned on a test totaling 50 points. 45 ÷ 50 = .90 or 90%
To calculate the true bearing between two points, you need to determine the angle between the north direction and the line connecting the two points. This can be done using trigonometry, where you calculate the difference in longitude and latitude between the points, and then use the arctan function to find the angle.
