Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1] In modern equipment this can be achieved by a hydraulics , but pulleys are generally used for simpler designs such as extendable ladders and amateur ...
The former is known as backward telescoping or time expansion, and the latter as is known as forward telescoping. [ 1 ] The approximate time frame in which events switch from being displaced backward in time to forward in time is three years, with events occurring three years in the past being equally likely to be reported with forward ...

In a railway accident, telescoping occurs when the underframe of one vehicle overrides that of another, and smashes through the second vehicle's body. The term is derived from the resulting appearance of the two vehicle bodies: the body of one vehicle may appear to be slid inside the other like the tubes of a collapsible telescope – the body ...
In mathematics, a telescoping series is a series whose general term is of the form = +, i.e. the difference of two consecutive terms of a sequence (). As a consequence the partial sums of the series only consists of two terms of ( a n ) {\displaystyle (a_{n})} after cancellation.
A telescoping stock (alternatively collapsible stock) is a buttstock that can retract into and shorten itself (telescoping) in order to make the whole weapon more compact. Telescoping stocks are useful in allowing a rifle , submachine gun , shotgun , or light machine gun to be stored or maneuvered in places it would otherwise have trouble fitting.
Limb telescoping is the progressive shortening of a phantom limb as the cortical regions are reorganized following an amputation. During this reorganization, proximal portions of the residual limb are perceived as more distal parts of the phantom limb.
