Bronze (brown) is an alloy with > 60% copper and mainly Sn added (and less Zn, Pb, Ni, P, Si).
Brass (yellow) is an alloy with > 56% copper and up to 40% Zn added (and less Sn, Pb, Ni, Fe, Al)
it is an alloyof
it is used in many devices such as
pumps
heat exchangers
pipe fittings
door fittings
it has high degree of resitance aganist corrison
I believe it is pooppo. Because pooppo is brown too. But they add a bit of wee wee too because it smells funny here's a picture of my pooppo which I enjoy eating
i have no idea but wiki answers dosent know either i have no idea but wiki answers dosent know either
it is a malleable metal .it is lustures and ductable . think so
me,me and more me
It truly could mean anything, depending on the material, to guide you in the right direction, material properties could include Malleability Compressive strength Ductility Fatigue limit Flexible modulus Flexible strength Fracture toughness Hardness Poisson's ratio Shear modulus Shear strength Softness Specific modulus Specific weight Tensile strength Yield strength Young's modulus Density Shear strain Permeability pH Surface Tension Melting Point Conductivity Hope that helps, there are many more properties that could be listed on this question!
SMAs have poor fatigue properties. While under the same loading conditions such as twisting, bending and compressing, SMA elements may survive for shorter time than a steel component. Moreover, the slow response characteristic of SMA actuators is incompatible with a high speed controller.
Lactic acid
I suppose that ths affirmation is not correct.
Iron is needed for hemoglobin and red cell formation so a deficiency in iron will lead to anemia. A insufficiency of oxygen being delivered to the body will result in fatigue.

Every material has a certain number of cycles that it can withstand. Fatigue failures occur suddenly without any prior warning when the particular number of cycles is exceeded. Gradual deformation or creep fracture occurs due to the presence of microcracks in the materials. As the load increases, these microcracks give in and undergo fracture. Fatigue failures could be common in automobile parts like crankshafts which fail after a certain milllion cycles ( Which could take around 5 years of running the car continuously for over a hundred miles everyday !) Answer Fatigue cycles can be applied to a part and the part will not have a crack. When the part has the received enought cycle loads, then it will initiate a crack. Continued cycle load applications will cause the crack to grow to failure. Fracture Mechanics is the study of the crack to grow to a critical size that will cause failure. Many structures, including aircarft, are allowed to have a fatigue crack that is inspected (including X-Ray) until it achieves a length that is a risk. Some material is ductile enough that a crack may grow for a long period of cycles. Brittle materials such as high-strength steels may only grow a crack 1/16-inch before it fails---and when it fails it almost shatters. Fatigue Damage is a term that applies to the theoretical life calcuation of a part under fatigue loading. When the faitgue life is calculated for a specific load(flight) spectrum, a damage factor is calcuated for 100 hours of operation. When the final damage fraction(factor) is determined, then this can be converted to a Fatigue Life or a projected time to failure. Fatigue Damage is invisible. During the fatigue loading period prior to development of a crack, there is no method to detect the part is about to crack. The best prevention is to accurately calculate or measure the stresses at the critical location and the stress cycles. A part that is loaded with high cyclic loads should be tested in a lab to determine its Endurance Limit.

A fatigue crack typically appears as a small, hairline fracture on the surface of the material. It can be perpendicular to the direction of the applied stress and may have a characteristic beach-mark pattern that indicates the progressive growth of the crack over time.
