Resultant force

Strong adsorbate-substrate forces lead to chemisorption, in which a chemical bond is fomied. By contrast, weak forces result inphysisorption, as one calls non-chemical physical adsorption. 

If the viscous contribution were absent, the solution to this problem would be characterized by a resonance frequency close to which the application of small driving forces results in displacements of large amplitude. 

Mechanical Considerations. The mechanical design of a fan and the various forces that fan parts must withstand are discussed ia Reference 14. The forces result from a combination of fluid, iaertial, and vibrational effects. 

When the isobars are essentially straight, the balance between the pressure gradient force and the coriolis force results in a geostrophic wind parallel to the isobars. 

Fig. 17 12. Balance of forces resulting in gradient wind around low pressure.

Fig. 17-13. Balance of forces resulting in gradient wind around high pressure. Note that the wind speed is greater for a given pressure gradient force than that around low pressure.

Thus, the force resultant produces twisting of the iaminate as evidenced by the K y term in addition to the usuai normal strains (extension) and (contraction) as readily seen in Figure 4-9a. 

When the linear variation of strain through the thickness, Equation (4.13), is substituted in Equation (4.103) and the resulting expressions for the layer stresses are integrated through the thickness, the force resultants are... 

The largest possible value of under uniaxial conditions is 150 ksi (1035 MPa). Thus, the outer layer can be stressed about an additional 149.4 ksi (1030.7 MPa). The corresponding change in the force resultant is obtained from Equation (4.135) as... 

When this change in force resultant is added to the force resultant at the knee, the largest laminate average stress is determined to be... 

Normal/auiiwg—basically dominated by tension and gravity forces results in the hanging tvall being displaced dotvnward relative to the footwall. 

All conditions listed in the section titled Load Capacities, subsection titled Mast and Derricks under Dynamic Conditions," are to be specified by the user. Forces resulting from wind and vessel motion are to be calculated in accordance with the formulas presented in the section titled Design Specifications, paragraphs titled Wind, Dynamic Loading (Induced by Floating Hull Motion). ... 

Acceleration is perhaps the best method of determining the force resulting from machine vibration. Accelerometers use piezoelectric crystals or films to convert mechanical energy into electrical signals and Figure 43.23 is a schematic of such a device. Data acquired with this type of transducer are relative... 

The process by which a material becomes eroded when exposed to the forces resulting from the collapse of cavitation bubbles proceeds in a number of stages according to Thiruvengadam and Preiser . In the first of these, the... 

As gas flows with fixed volumetric flow rate through an orifice gas sparger, bubbles are formed with diameter Analysis of bubble formation is based on the balance of buoyant force, as the bubbles leave the orifice and rise through the media (irApgDl)/6 with rest of the forces resulting from the surface tension, Trad. 

Movement of colloidal suspended particles due to forces resulting from collision of colloids and molecules of suspended medium (usually water). 

For the flow of a fluid in a pipe of length / and diameter d, the total frictional force at the walls is the product of the shear stress R and the surface area of the pipe (Rndl). This frictional force results in a change in pressure A Pf so that for a horizontal pipe ... 

This is, of course, the Reynolds number, which determines the nature of the flow, as shown in Chapter 3. In similar fashion, the constancy of the ratios between other forces results in Froude and Weber numbers as follows ... 

A shear force resulting from the shear stress Ro acting at the surface. This is a retarding force and therefore Rq is negative.
