Abstract: The side‐sway effective length of a crane jib is investigated. For jibs with uniform cross section, restraints provided by the derrick, hoist cable and tower are also considered. When the jib end is completely fixed at the ...

Abstract: The moment‐ratio method developed is a numerical procedure to determine the natural frequencies of continuous orthotropic and isotropic plates. The basic concept employs dynamic flexibility functions at the panel joints. ...

Abstract: The numerical formulas are presented for quick determination of natural frequencies of orthotropic and isotropic continuous uniform plates. A one‐way continuous plate consists of two types of independent vibration modes ...

Abstract: The finite element method was used to analyze the stresses in a rock bit cutter tooth under applied loads. Detailed finite element models were constructed to allow accurate descriptions of the ...

Abstract: A first known investigation on the three-dimensional vibration characteristics of conical shell panels is reported. A linear frequency equation is derived based on an exact three-dimensional, ...

Abstract: Exact solutions are obtained for a model of the longitudinal displacement along an elastic tapered bar due to a force applied at its blunt end. A formula for velocity amplification is given; ...

Abstract: We propose a mathematical model for pendelluft flow in a single airway bifurcation. The model is motivated by an apparatus used in an experimental study of the pendelluft by Ultman et al. ...

Abstract: We study the symmetries admitted by the amplitude equations governing the nonlinear nonplanar parametric responses of an inextensional beam (Nayfeh and Pai, 1989). As a result of these symmetries, ...

Abstract: The general problem of the two-dimensional state of stress in a strip of elastic material under normal loading is considered. A series expansion of displacement functions generated along lines ...
