  2. Cantilever - Wikipedia

    en.wikipedia.org/wiki/Cantilever

    The top and bottom example may be considered structurally equivalent, depending on the effective stiffness of the spring and beam element. A cantilever is a rigid structural element that extends horizontally and is unsupported at one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached.

  3. Euler–Bernoulli beam theory - Wikipedia

    en.wikipedia.org/wiki/Euler–Bernoulli_beam_theory

    Another important class of problems involves cantilever beams. The bending moments ( M {\displaystyle M} ), shear forces ( Q {\displaystyle Q} ), and deflections ( w {\displaystyle w} ) for a cantilever beam subjected to a point load at the free end and a uniformly distributed load are given in the table below.

  4. Bottom type - Wikipedia

    en.wikipedia.org/wiki/Bottom_type

    In type theory, a theory within mathematical logic, the bottom type of a type system is the type that is a subtype of all other types. [ 1 ] Where such a type exists, it is often represented with the up tack (⊥) symbol.

    For example, in the case of design for fire a load case of 1.0 x Dead Load + 0.8 x Live Load may be used, as it is reasonable to assume everyone has left the building if there is a fire. In multi-story buildings it is normal to reduce the total live load depending on the number of stories being supported, as the probability of maximum load ...

    Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International ...

  7. Cantilever method - Wikipedia

    en.wikipedia.org/wiki/Cantilever_method

    The cantilever method is an approximate method for calculating shear forces and moments developed in beams and columns of a frame or structure due to lateral loads. The applied lateral loads typically include wind loads and earthquake loads, which must be taken into consideration while designing buildings.

    For example: "All humans are mortal, and Socrates is a human. ∴ Socrates is mortal." ∵ Abbreviation of "because" or "since". Placed between two assertions, it means that the first one is implied by the second one. For example: "11 is prime ∵ it has no positive integer factors other than itself and one." ∋ 1. Abbreviation of "such that".

  9. Gravitropism - Wikipedia

    en.wikipedia.org/wiki/Gravitropism

    [4] [9] In stems, the auxin also accumulates on the lower side, however in this tissue it increases cell expansion and results in the shoot curving up (negative gravitropism). [ 10 ] A recent study showed that for gravitropism to occur in shoots, a lot of an inclination, instead of a weak gravitational force, is necessary.
