WebThe coefficients of static friction between the two beams and between the lower beam and the bed of the trailer are 0.25 and 0.30, respectively. Knowing that the load does not shift, determine (a) the maximum acceleration of the trailer and the corresponding tension in the cable, (b) the maximum deceleration of the trailer. Verified answer. Webγ L is the surface energy (tension) of the liquid phase, γ S is the surface energy of the solid phase, γ SL is the interfacial surface tension, and W a is the work of adhesion. A rise in the interfacial attraction results in an increase in the work of adhesion. Equation (3.10) can be rewritten to determine the work of cohesion (W c) when the two phases are identical …

WebNov 5, 2024 · Attractive forces between molecules of the same type are called cohesive forces. Attractive forces between molecules of different types are called adhesive forces. Surface tension is a contractive tendency of the surface of a liquid that allows it to resist an external force. Capillary action, or capillarity, is the ability of a liquid to flow ...
WebFeb 20, 2024 · Surface tension is proportional to the strength of the cohesive force, which varies with the type of liquid. Surface tension γ ¯ is defined to be the force F per unit length L exerted by a stretched liquid membrane: (11.8.1) γ = F L. Table 11.8. 1 lists values of γ ¯ for some liquids.
