Tensile strength Sentence Examples
Most metals when molten are capable of dissolving at least small proportions of carbon, which, in general, leads to a deterioration in metallicity, except in the case of iron, which by the addition of small percentages of carbon gains in elasticity and tensile strength with little loss of plasticity.
Its tensile strength is higher than that of steel.
Such an alloy can be cast like ordinary bronze, but excels the latter in hardness, elasticity, toughness and tensile strength.
The safe tensile strength of Portland cement concrete would be something like one-tenth of its compressive strength, and might be far less.
On this account it is usual to neglect the tensile strength of concrete in designing structures, and to arrange the material in such a way that tensile stresses are avoided.Advertisement
But it is difficult and expensive to work up into various forms. Concrete has been avoided for making beams, slabs and thin walls, just because its deficiency in tensile strength doomed it to failure in such structures.
Assuming the materials to be of equal tensile strength per unit of area - hard-drawn copper is stronger, but has a lower conductivity - the adoption of aluminium thus leads to a reduction of 52% in the weight, a gain of 60% in the strength, and an increase of 26% in the diameter of the conductor.
The tenacity or tensile strength increases till the carbon-content reaches about 1.25%, and the cementite about 19%, and then in turn falls, a result by no means surprising.
Nickel steel, which usually contains from 3 to 3.50% of nickel and about 0.25% of carbon, combines very great tensile strength and hardness, and a very high limit of elasticity, with great ductility.
Hence, as with the progressive transfer of the carbon from the graphitic to the cementite state in our imaginary series of cast irons, the combined carbon present in the matrix increases, so does the tensile strength of the mass as a whole for two reasons; first, because the strength of the matrix itself is increasing (DE), and second, because the discontinuity is decreasing with the decreasing proportion of graphite.Advertisement
As regards both tensile strength and ductility not only the quantity but the distribution of the graphite is of great importance.
To sum this up, as graphite is replaced by carbon combined as cementite, the hardness, brittleness and density increase, and the expansion in solidification decreases, in both cases continuously, while the tensile strength increases till the combined carbon-content rises a little above I %, and then in turn decreases.
It is, however, principally a cordage fibre, and in tensile strength it is second only to manila hemp; but it does not bear well the alternations of wet and dry to which ship-ropes are subject.
Such composite structures take advantage at once of the high tensile strength of iron and of the high compressive strength of cement mortar.
By the addition of a small quantity of silicon the tensile strength of copper is much increased; a sample of such silicon bronze, used for telegraph wires, on analysis was found to consist of 99.94% of copper, 0.03% of tin, and traces of iron and silicon.Advertisement
Therefore, most glass breakage is due to tensile strength failure.
Ideal for embroidery machines; it has a high tensile strength and excellent color fastness.
Chains rarely fail because they do not have sufficient tensile strength.
Most metals when molten are capable of dissolving at least small proportions of carbon, which, in general, leads to a deterioration in metallicity, except in the case of iron, which by the addition of small percentages of carbon gains in elasticity and tensile strength with little loss of plasticity (see Iron).

Rivets are either of wrought iron or of extra soft steel, with an ultimate tensile strength of 55,000 lb per sq.
The glass fibers, which are chopped in situ by specially designed applicator vehicles, give tensile strength to the surface and resist cracking.Advertisement

The tensile strength of the alloys is high, making possible the drawing of very fine wire.
Composite planes have a high tensile strength with a sturdy body.
Something soft is of course nice, but not too soft, otherwise your muscles lose their tensile strength and you'll look like the hunchback of Notre Dame in a year's time.
It would appear, however, that the finest " wild " Para rubber as a rule possesses greater tensile strength than the " plantation " rubber.
