The displacement u ( for the simply supported beam of Figure P3.33 (a) loaded by an end moment Mo is given by 2 Figure P3.33 (a) Use this result and Maxwell's reciprocal theorem to find where the force F should be placed on the beam of Figure P3.33 (b) if the slope of the beam at B is to be a maximum. WebBetti's theorem, also known as Maxwell–Betti reciprocal work theorem, discovered by Enrico Bettiin 1872, states that for a linear elastic structure subject to two sets of forces {Pi} i=1,...,n and {Qj}, j=1,2,...,n, the workdone by the set P through the displacements produced by the set Q is equal to the work done by the set Q through the … thealtening account

Web如在某线性弹性体上作用两组广义力，则第一组力在第二组力引起的位移上所作的功，等于第二组力在笫一组力引起的位移上所作的功。这一定理适用于线弹性体小变形的情况。若上述两组广义力都只包含一个广义力且彼此相等，此定理即化为位移互等定理。 Web30 jan. 2024 · The Reciprocal Theorem: let's start by dividing Equation ( 1) by d x, while keeping y constant. The second term in the equation would trivially be zero, since d y = 0, and we'd get the trivial result: ( ∂ f ∂ x) y = ( ∂ f ∂ x) y. A more interesting result appears if we carefully divide Equation ( 1) by d f, but we still keep y constant. WebThe reciprocal theorem has been proved in various ・‘lds, such as statistical mechanics, quantum mechanics, and electromagnetism.4Here we introduce the theorem for elec- tromagnetism.

Web以上是maxwell betti reciprocal theorem（纪念英国物理学家James Clerk Maxwell,1831-1879）。推广完整的表达应该就是所谓“功的互等定律”，即本例中第二步P2加载时，P1在C1做的功，与反过来先作用P2，再作用P1时，P2在C2做的功相等（这时P1P2不要求为单位力，可以是大小不同的载荷）。 Web30 dec. 2024 · Solution: With the reference to figure 1, the equivalent resistance across x-y is given by. Hence we observe that when the sources was in branch x-y as in figure 1, the a-b branch current is 1.43A; again when the source is in branch a-b (figure 2), the x-y branch current becomes 1.43A. This proves the reciprocity theorem.
