Using a downhole motor with bent housing most effectively requires determination of its deflecting performance and designing the bottom hole assembly according to the expected deflection rate.

Alison Gibbings and Massimiliano Vasile, aerospace engineers at the University of Strathclyde, UK, new solution is a 500-kilogram swarm of fingernail-sized spacecraft would, they calculate, deflect a ...

In the previous discussions of solution of beam-column, the basic differential equation of beam-column and its boundary conditions are generally expressed in terms of the lateral deflection w as can ...

In Chap. 3, the special case of flexural-torsional buckling strength of a plane beam-column subjected to loading in its plane is approached and solved from the standpoint of bifurcation. There, the ...
