Cantilever method

The force and moment ia a constrained system can be estimated by the cantilever formula. Leg MB is a cantilever subject to a displacement of and leg CB subject to a displacement Av. Taking leg CB, for example, the task has become the problem of a cantilever beam with length E and displacement of Av. This problem caimot be readily solved, because the end condition at is an unknown quantity. However, it can be conservatively solved by assuming there is no rotation at poiat B. This is equivalent to putting a guide at poiat B, and results ia higher estimate ia force, moment, and stress. The approach is called guided-cantilever method. 

The elastic properties of the substrate can be determined more accurately than those of the film. Hence, in principle, the magnetoelastic coupling parameter By-2 can be determined more accurately than the magnetostriction coefficient ky-2. An analogous conclusion can be drawn with respect to bending experiments (see e.g. section 3.1 the magnetoelastic cantilever method). 

In this measurement, the hysteresis problem was solved by applying a constant transverse field. In eq. (18), this transverse field does not occur due to cancelling of terms. The same holds for the (in-plane) anisotropy and the shape anisotropy. Baril et al. (loc. cit.) claim that this is a reliable method, giving results consistent with the cantilever method and with a sensitivity better than I x 10-7. It is perhaps worthwhile, however, to consider all... 

In some textile production laboratories single reference standards or a simple set of hand standards with different hand values is used. This set of standards is produced from the same fabric as the one being evaluated by applying the same softener at incremental concentrations. If the softener is used in combination with other finishes, the concentration of the other fmishes must be held constant. Relatively simple methods to evaluate only the bending properties of fabric (flex rigidity) are the cantilever method and a similar device called Softometer, which are described in Chapter 4 on hand building.

The effects of a fabric stiffening treatment can be quantified by the cantilever method described in ASTM 01388-96. A sample of specified length and width is placed on top of the test device. The device has a horizontal surface connected to a downward incline. The fabric is pushed over the incline until the sagging leading edge just touches the inclined plane of the device. The length of fabric that has passed over the point where the horizontal and incline meet is used to calculate the fabric s flexural rigidity. 

Simpson s [10] values of Eb for human hair were higher, 5.35 x 10 dynes/cm. However, Simpson used the vibrating cantilever method. This procedure produces Eb values that vary with vibrational frequency. He also used a lower RH (50%).

Apart from Cantilever method, a number of stiffness testing instruments have been designed, developed and studied. The initial research shows stiffness as one of the factors determining drape characteristics of fabrics. The other instruments used for the measurement of the 2-D drape measurement are Heart Loop tester [9], Schiefer Flexometer [10], Planoflex [11, 12] and MIT Drapemeter [9, 13].
