For a beam in pure bending, the normal stress in the y-direction (σyy) and the shear stress in the xy-plane (τxy) must be zero. This requires that c1, c2, and c3 be zero. These conditions yield a linear variation of the stress σxx with respect to the vertical (y) direction,...
The amount of time that it takes for the sound energy density to decay by a factor of 106 (i.e., 60 db) is called the reverberation time of the room. The sound energy density concept was used by Sabine in his fundamental discoveries on reverberation. He found that sound fills a ...
There is a new and better way to access online help from theEquations window. Double-click on any built-in or library function, property function, fluid name, directive or variable to select it. Then right-click to bring up the Equations window popup menu. If help is available for the it...
For example, during loading you will be able to preload it up to a certain point but not all the wire will reach the same tension due to friction so you'll be limited by the point at maximum stress. As time goes on, I believe the tension will tend to equalize so you might loose ...
For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μs , is usually higher than the coefficient of kinetic friction. Material Sliding Dry Lubricated Aluminum on aluminum - - Canvas belt on rubber lagging...
1.Based on thermodynamics and combined with empirical equation of state,equation parameters are appropriately modified and a modified equation of state with multiple parameters is derived, which is more suitable for use.从统计热力学的观点出发,结合经验的状态方程,对方程参数作出适当的修正,得到一个改进的...
The model was continuously revised based on the model fitting degree, and the final influencing factors for decisional conflict included in the path analysis were family monthly income, the level of eGFR, the level of cTnI, the score of BHLS, the score of MoCA, and the score of PSSS. The...

Therefore, more detailed treatises on optics and electromagnetic waves now generally start with a microscopic description of the wave equations, for example, the book by Stone [1]. While there is little disagreement in the literature on the microscopic equations, the macroscopic equations often ...
