This paper contains a strain gradient theory to capture size effects in rotating nanodisks of variable thickness under thermal and mechanical loading. Material properties of nanodisks have been taken homogeneous material. The strain gradient theory and the Hamilton’s principle are employed to derive the governing equations. Due to complexity of the governing differential equation and boundary c...

Abstract Hyperbolic nonlocal theory is applied in this paper to calculate deflections functionally graded nanobeams under uniform load. The developed using the work done principle conjunction with Eringen’s theory. Free stress conditions on upper and lower surfaces are achieved by current hypothesis. Deflection of beam estimated Navier’s approach considering simple ends nanobeam. Solutions foun...

Nanobeams are now widely used in numerous vibration frequency research. In this study, an eigenvalue problem has to determine the analysis of buckyball and spring attached end nanobeam. The frequencies system may be discovered using a single (2x2) matrix problem. A mathematical method for analyzing sensors nanobeams is presented paper. results, which obtained showed result that compatible with ...

In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...
