What else can I help you with?
The volume of a cylinder increased by 8 times the original volume How many times greater are each of the dimensions of that new cylinder?
the dimensions of the cylinder would be 2 times greater. We just had a test on this stuff and this was one of the questions.
Spearman-Brown formula ptherwise called as split half method?
not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.
What is the formula of mark up percent?
what you do is you divide 100 by the amount the test was out of then times your answer by your mark
How do you calculate linear viscoelastic region?
To calculate the linear viscoelastic region (LVR), you typically perform a strain sweep test using dynamic mechanical analysis (DMA) or oscillatory shear rheometry. By applying varying strain amplitudes and measuring the resulting stress, you identify the range where the material exhibits a linear response—characterized by a constant ratio of stress to strain. This is often determined by plotting the storage modulus (G') and loss modulus (G'') against strain and identifying the strain range where both moduli remain relatively constant. The LVR is crucial for ensuring accurate material characterization without introducing nonlinear effects.
Different between cube and cylinder in concrete compressive test?
The difference in compressive strength is due to the difference between the modulus of elasticity of concrete and that of the steel which is used to apply the compressive force on the concrete. The pressure applies a lateral confinement pressure which is equal to d/3 meaning that for the cylinder, 2d/3 is confined leaving d/3 unconfined whereas for the cylinder 2d/3 is confined means all of the cube is confined. This leads to the cube having a higher compressive strength that the cylinder. For more information, try to read about the triaxial test and the effect of confinement on the compressive strength of soil samples.

How do you calculate tensile strength of a ismc 100 channel?
the most effective way to find out is through Westermann Tables....the cross section area of all the standard mechanical manufacturing parts is given..channels.. angles etc....once you know the area and the UTS(ultimate tensile strength) of MS(mild steel)...you know the ans.... help yourself.
Why Tensile Properties of most brittle materials are accessed by transverse bending test and not ascertain by tensile test?
why the tensile properties of most brittle materials are accessed by transverse bending tests and not ascertain by tensile tests
How tensile test is made on a material?
A sample coupon of the material is made up, usually in the shape of a dog bone per standards of ASTM. The sample is placed into a tensile testing machine such as made by Instron. The sample is grasped at the ends of the dog bone. This machine has a load cell in it, and the machine is commanded to move relative to its fixed base and stretch the sample, resulting in stress and strain of the material. When the material breaks, the tensile strength is noted. The break stress is the strength divided by the area of the sample of the dog bone center section. If you want yield point, this can be obtained also from plots integral with the software of the test set up. If you want to measure tensile modulus, you would need a strain gage device or extensometer . This is not needed for tensile strength only.
What is importance of tensile strength test?
yes
What is ASTM standard for tensile test?
E8
What is the formulae to calculate tension young's modulus?
Young's modulus is determined experimentally by applying tensile strain (pulling on the ends) to a number of samples of the material under investigation and plotting the strain versus the elongation and taking the slope of the central part of the plot.
How would you carry out a elasticity test?
To carry out an elasticity test, you would typically apply a known amount of force or stress to the material and measure the resulting deformation or strain. By plotting stress vs. strain on a graph, you can determine the material's elasticity, including its Young's modulus and ultimate tensile strength. This test is commonly performed using a universal testing machine according to specific standards such as ASTM or ISO.
