The forces that cause adhesion and cohesion can be divided into several types.

In addition to the cumulative magnitudes of these intermolecular forces, there are also certain emergent mechanical effects.</li> <li><a href="/facts/Aggregate_(composite)/dKfhlNIw">Aggregate (composite)</a> – is the component of a <a href="/facts/Composite_material/UBysQldh">composite material</a> that resists compressive stress and provides bulk to the composite material.

Its mode of deflection is primarily by <a href="/facts/Bending/gxA8Pks1">bending</a>. The loads applied to the beam result in <a href="/facts/Reaction_force/g2rCCqwq">reaction forces</a> at the beam's support points. The total effect of all the forces acting on the beam is to produce <a href="/facts/Shear_force/hVKPYRar">shear forces</a> and <a href="/facts/Bending_moment/6tmafWtR">bending moments</a> within the beam, that in turn induce internal stresses, strains and deflections of the beam. Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material.</li> <li><a href="/facts/Bearing_capacity/dNPtXzze">Bearing capacity</a> – is the capacity of <a href="/facts/Soil/5Ddpr3QM">soil</a> to support the <a href="/facts/Structural_load/MAxjDyhc">loads</a> applied to the ground. The bearing capacity of soil is the maximum average contact <a href="/facts/Pressure/eyc37GRG">pressure</a> between the <a href="/facts/Foundation_(architecture)/ACVkQsDy">foundation</a> and the soil which should not produce <a href="/facts/Shear_strength_(soil)/3h6ehUqy">shear</a> failure in the soil. <i>Ultimate bearing capacity</i> is the theoretical maximum pressure which can be supported without failure; <i>allowable bearing capacity</i> is the ultimate bearing capacity divided by a <a href="/facts/Factor_of_safety/QzjeEqRp">factor of safety</a>. Sometimes, on soft soil sites, large settlements may occur under loaded foundations without actual shear failure occurring; in such cases, the allowable bearing capacity is based on the maximum allowable settlement. There are three modes of failure that limit bearing capacity: general shear failure, local shear failure, and punching shear failure.</li> <li><a href="/facts/Bending/gxA8Pks1">Bending</a> – In <a href="/facts/Applied_mechanics/rUlbDdob">applied mechanics</a>, bending, (also known as flexure), characterizes the behavior of a slender <a href="/facts/Structural/xQDPtqDQ">structural</a> element subjected to an external <a href="/facts/Structural_load/MAxjDyhc">load</a> applied perpendicularly to a longitudinal axis of the element.</li> <li><a href="/facts/Bending_moment/6tmafWtR">Bending moment</a> – is the reaction induced in a <a href="/facts/Structural_element/BdYjdKrq">structural element</a> when an external <a href="/facts/Force/533Q1uzq">force</a> or <a href="/facts/Moment_of_force/KcrcvNtV">moment</a> is applied to the element causing the element to <a href="/facts/Bending/gxA8Pks1">bend</a>.<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a><a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a></li> <li><a href="/facts/Benefit%25E2%2580%2593cost_analysis/xjHXgIAF">Benefit–cost analysis</a> – Cost–benefit analysis (CBA), sometimes called benefit costs analysis (BCA), is a systematic approach to estimating the strengths and weaknesses of alternatives used to determine options which provide the best approach to achieving benefits while preserving savings (for example, in transactions, activities, and functional business requirements).<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> A CBA may be used to compare completed or potential courses of actions, or to estimate (or evaluate) the value against the <a href="/facts/Cost/V1GX4vhw">cost</a> of a decision, project, or policy.

They do not have any sort of pre-defined configuration in the way that a <a href="/facts/Truss_bridge/2ufXUJMQ">Pratt truss</a> does. Rather, bents are simply cross-sectional templates of structural members, i.e., rafters, joists, posts, pilings, etc., that repeat on parallel planes along the length of the structure. The term bent is not restricted to any particular material. Bents may be formed of wooden piles, timber framing,<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> steel framing, or even concrete.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a></li> <li><a href="/facts/Bistable_structure/mmL2HEp4">Bistable structure</a> –</li> <li><a href="/facts/Brick/2CBPgDIK">Brick</a> – is building material used to make walls, pavements and other elements in <a href="/facts/Masonry/TlaDzpUp">masonry</a> construction.
