Dimensional analysis is often useful to verify empirical formulae and relationships obtained by regression analysis of raw data.Answer and Explanation: Let's first find the dimensions of momentum per unit area per unit time. Note that momentum is the ...

When a coil is energized, the Lorentz force gives rise to a body force, that is a force per unit volume, of which the radial component Fr = JBz is the most important. This force tends to explode the coil. If the coil is considered as a rigid cylinder with a hole in it, this forc...
The internal forces per unit area present in a material exposed to external forces or loads. In the International Standard of Units (SI), its unit of measurement is Pascals; the English System expresses stress in pounds per square inch, or PSI. Structural Member: The constituent part of a...
BEAM188 is a versatile two-node beam element applicable to three-dimensional analyses. It can adopt linear, quadratic, or cubic formulations and is based on Timoshenko beam theory, which incorporates shear deformation effects. This element supports six or seven degrees of freedom per node, making ...
Similarly, the force per unit area required to break two cells adherent to each other through specific ligand-receptor binding can be calculated. Our technique thereby is relevant in physiological scenarios and can be applied, for example, to evaluate forces required to disrupt cancer cell-...

which is expressed by F1 in the physical model. The formula for calculating the pressure is F = P × S; this is thus the product of the pressure per unit area and the contact area. The influencing factors include vessel diameter (D), blood pressure (BP) and vessel clamp width...
If we repeat the argument above using both the attractive and repulsive parts of the van der Waals force, i.e., both terms in the Lennard-Jones expression (2.1), the expression for the force per unit area between the infinite surfaces becomes (Maugis [108]) (3.4)F¯=−A6πD3+BD...
The work of the force f per unit time is equal to the product f·v, where v is the velocity of the particle. Thus we must have (84.1)∑afa·va¯=−23c3d¨2¯ (where the sum goes over all the particles of the system). It is easy to see that this requirement is satisfied ...
