Analysis of Multi-Representation-Based E-book Needs on Basic Physics Materials, Department of Physics Education, Musamus University

This study aims to describe the analysis of development needs and produce multi-representation-based e-books in basic physics courses. This study uses a mixed-method, explanatory sequential design model. This research is still limited in definition, namely needs analysis before developing multi-representation-based e-books. The development of a multi-representation-based basic physics e-book is based on several aspects of student needs including aspects of the student basic physics lecture process, student difficulties in understanding basic physics material, learning resources used by students in studying basic physics material: student needs related to basic physics e-book needs integrated multi-representation in solving Physics problems. The subjects of this study were 76 students of the Department of Physics Education, Musamus University, Merauke. The results of the analysis show that a total of 91.1% of students of the physics education department at the University of Musamus need multi-representation-based e-books in the basic physics learning process. This is supported by student response data. First, the majority of student learning processes are still learning using conventional methods in lectures, so they need interactive media to improve the quality of learning. Second, the majority of students only have access to learning resources in the form of textbooks in lectures. Third, the majority of students have difficulties understanding physics concepts. Fourth, students need multi-representation-based e-books in Physics lectures

Free vibration of symmetric angly-plane layered truncated conical shells under classical theory

Truncated conical shell finds wide ranging of engineering applications. They are used in space crafts, robots, shelters, domes, tanks, nozzles and in machinery devices. Thus, the study of their vibrational characteristics has long been of interest for the designers. The use of the lamination for the structures leads to design with the maximum reliability and minimum weight. Moreover, the study of free vibration of laminated conical shells has been treated by a number of researchers. Irie et al. (1982) studied free vibration of conical shells with variable thickness using Rayleigh-Ritz method of solution. Wu and Wu (2000) provided 3D elasticity solutions for the free vibration analysis of laminated conical shells by an asymptotic approach. Wu and Lee (2001) studied the natural frequencies of laminated conical shells with variable stiffness using the differential quadrature method under first-order shear deformation theory (FSDT). Tripathi et al. (2007) studied the free vibration of composite conical shells with random material properties of the finite element method. Civalek (2007) used the Discrete Singular Convolution (DSC) to investigate the frequency response of orthotropic conical and cylindrical shells. Sofiyez et al. (2009) studied the vibrations of orthotropic non-homogeneous conical shells with free boundary conditions. Ghasemi et al. (2012) presented their study of free vibration of composite conical shells which was investigated under various boundary conditions using the solution of beam function and Galerkin method. Viswanathan et al. (2007, 2011) studied free vibration of laminated cross-ply plates, including shear deformation, symmetric angle-ply laminated cylindrical shells of variable thickness with shear deformation theory using the spline collocation method. In the present work, free vibration of symmetric angle-ply laminated truncated conical shells is analyzed and displacement functions are approximated using cubic and quantic spline and collocation procedure is applied to obtain a set of field equations. The field equations along with the equations of boundary conditions yield a system of homogeneous simultaneous algebraic equations on the assumed spline coefficients which resulting to the generalized eigenvalue problem. This eigenvalue problem is solved using eigensolution technique to get as many eigenfrequencies as required. The effect of circumferential mode number, length ratio, cone angle, ply angles and number of layers under two boundary conditions on the frequency parameter is studied for three- and five- layered conical shells consisting of two types of layered materials
