200 x 10^6 MPa
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
the modulus for brass is 91*109 Nm-2
Stress is the amount of force per unit area (N/mm2; lb/ft2) Strain is the unitless change in length resulting from the application of a force (movement in unit length / original unit length) Young's Modulus relates the two (stress / strain)
The fulcrum is the part of a lever that does not move. The effort is the name of the force applied to a lever. The load is the weight of the object being lifted by a lever.
The hardness of materials is a function of their elastic modulus. As such a number of tests are used to measure hardness. Relative hardness can be assessed by the scratch test where one material or mineral is used to scratch another. As such, the material that manages to scratch the other is harder, while the one that is scratched is softer. This comparative or relative hardness method is the basis of the Mohs hardness scale. More quantitative methods of assessing the hardness of materials are based on the height of rebound of a hammer of known mass allowed to fall from a fixed height (which imparts a known energy into the material), where the height to which it rebounds is dependant on the properties of the material. As such, the higher the rebound, the larger the elastic modulus of the material and the harder the material. Two examples of tests which use this methodology are the Schmidt hammer test and the Shore scleroscope test. Another common method used to measure the hardness of materials is to assess the depth of indentation of a tool of fixed dimensions at a specified applied load into the material of interest, where the larger the size of indentation, the softer the material. This methodology is commonly used for testing metals and forms the basis of the Vickers, Brinell and Rockwell hardness tests. Please see the related links for more information.
CRCA Sheet is ferrous, it is a steel.
cold rolled close annealed -CRCA
CRCA - Cold Rolled Close Annealed Sheet Steel.
CRCA means "cold rolled close annealed".
Young's modulus
the dimensions of Young's Modulus of Elasticity = (M).(L)^(-1).(T)^(-2)
Young's modulus
Modulus of elasticity will be 2.06*10^5 N/mm2
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
The modulus of elasticity is the slope of the linear portion of the curve (the elastic region).
