  2. Wedge - Wikipedia

    en.wikipedia.org/wiki/Wedge

    Consider a block that is to be lifted by a wedge. As the wedge slides under the block, the block slides up the sloped side of a wedge. This lifts the weight F B of the block. The horizontal force F A needed to lift the block is obtained by considering the velocity of the wedge v A and the velocity of the block v B. If we assume the wedge does ...

    en.wikipedia.org/wiki/Simple_machine

    The screw's self-locking property is the reason for its wide use in threaded fasteners like bolts and wood screws In many simple machines, if the load force F out {\displaystyle F_{\textrm {out}}} on the machine is high enough in relation to the input force F in {\displaystyle F_{\textrm {in}}} , the machine will move backwards, with the load ...

    Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]

  6. Structural engineering - Wikipedia

    en.wikipedia.org/wiki/Structural_engineering

    Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made structures. Structural engineers also must understand and calculate the stability , strength, rigidity and earthquake-susceptibility of built structures for ...

    In the milieu of levering methods, there are those that lift the block incrementally, as in repeatedly prying up alternating sides of the block and inserting wooden or stone shims to gradually move the stone up one course; and there are other methods that use a larger lever to move the block up one course in one lifting procedure.
