1. Videoanálise do voo de um fidget spinner: torque e momento angular
Resumo Poderia o mundialmente famoso brinquedo fidget spinner ser usado em sala de aula para ilustrar os conceitos de momento de inércia, torque e momento angular? Curiosamente, foram raros os artigos de ensino relacionados ao tema que foram publicados até a presente data. Neste trabalho apresentamos uma situação real composta por duas configurações ex

2. Satellite Inertia Parameters Estimation Based on Extended Kalman Filter
ABSTRACT: The moment of inertia parameters play a critical role in assuring the spacecraft mission throughout its lifetime. However, determination of the moment of inertia is a key challenge in operating satellites. During satellite mission, those parameters can change in orbit for many reasons such as sloshing, fuel consumption, etc. Therefore, the inertia

3. Moment of inertia through scaling and the parallel axis theorem
Abstract A right triangular plate scaled by a factor two generates a bigger plate composed of four triangular plates the same size as the original. By using dimensional analysis we write the moment of inertia around the center of mass, for the original and the bigger plate, in terms of a common unknown parameter. Through the parallel axis theorem we relate t

4. Numerical analysis of RC plane structures: a concentrated nonlinear effect approach
Abstract The present work aims to study the nonlinear behavior of reinforced concrete structures via Refined Plastic Hinge Method (RPHM). Pseudo-springs are used at the finite element ends, where the gradual loss of stiffness is determined by the combination of the normal force and bending moment (NM) in the cross section. The limiting of the uncracked, ela

5. Influence of nails size and layout to obtain the reduction coefficient of moment of inertia for timber beams with composite cross section
ABSTRACT A significant portion of rural building’s roof is supported by timber trusses. Increasing distance between the trusses can be achieved by using composite cross sections ("T" and "I") for beams. With this, it is possible to reduce the number of columns and trusses, bringing significant savings in material and the desired cost reduction, mainly usin

6. The inertial effect of acceleration fields on a self-decoupled wheel force transducer
AbstractWheel force transducer (WFT) is a tool which can measure the three-axis forces and three-axis torques applied to the wheel in vehicle testing applications. However, the transducer is generally mounted on the wheel of a moving vehicle, when abruptly accelerating or braking, the mass/inertia of the transducer itself has extra effects on the sensor resp

7. Explicit expression for effective moment of inertia of RC beams
AbstractDeflection is an important design parameter for structures subjected to service load. This paper provides an explicit expression for effective moment of inertia considering cracking, for uniformly distributed loaded reinforced concrete (RC) beams. The proposed explicit expression can be used for rapid prediction of short-term deflection at service lo

8. Study on the capacity of cold-formes steel built-up battened colums under axial compression
This paper presents the theoretical and numerical investigation results of the pin ended cold-formed steel built-up battened columns under axial compression. The finite element model was developed using the finite element software ABAQUS. The comparison of finite element analysis results match with the test results available in the literature shows that the

10. Aeroelastic modeling and experimental analysis of a flexible wing for wind tunnel flutter test.
The objective of this work is to investigate the flutter phenomena experimentally, which will unify high aspect ratio wings design for wind tunnel flutter tests (Dowell and Tang, 2002), cheaper aeroelastic models construction and a procedure used by Sheta, Harrand, Thompson and Strganac (2002) to identify the flutter onset power spectral density versus the f
