Pole Placement Approach for Controlling Double Inverted Pendulum
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 2 In this paper, we present in-depth analysis of the classical double inverted pendulum (DIP) system using the DIP modeling and the pole placement approach to control it. The double inverted pendulum system has the characteristics of multiple variables, non-linear, absolute instability; it can reflect many key issues in the progress of control, such as stabilization, non-linear and robust ...

Investigation of Stresses in a Beam with Fixed Connection Using Finite Difference Technique
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 2 In this study a simple rectangular beam has been analyzed. For simplicity two dimensional plane strain problem is considered. The beam is fixed at the left and right edges of the bottom surface. Uniformly distributed load is applied along the length of the beam. A new formulation, known as displacement potential function formulation has been used here. Stresses and displacements at diffe...

Thickness and Shape Optimization of Filter Sheet by Non-Linear FEA
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 1 Filter Sheets are non standard components and hence the guidelines for design are loose under the ASME and the TEMA code. The usual engineering practice is to extend the ever current design is available with an increased factor of safety. However this results in excessively heavy designs, resulting in increasing costs (e.g. Material, transport, assembly and installation).Hence in such de...

Mathematical Correlations Developed For Solar Chimney Power Plant – A Critical Review
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 13 Issue: 1 A solar chimney power plant consists of a large greenhouse-type collector surrounding a tall chimney. The air, heated within the collector, passes through an inlet guide vane (IGV) cascade and then through a transition section to a turbine that powers a generator. The transition section contains the turbine inlet guide vanes that support the whole chimney and guides the flow entering the...

Design, Construction and Modeling of a Mechanical Portable Barbecue Machine
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 7 It is an undisputable fact that the existing skewers we come across our various homes and roadsides are heavy and thus, are not easily carried around. Their source of heat which is charcoal is also a danger to the environment in that the process of even acquiring the charcoal promotes deforestation which is tantamount to global warming. The operator is exposed to unfriendly working condi...
