In the current scenario of educational institutions, multimedia has dig up its own kind of space in some or the other way as a tool of educational technology. Multimedia has overcome the barriers of time and space and provides evidence to be accepted as an anytime and anywhere tool for educating multi-disciplinary masses. The process of knowledge acquisition becomes more efficient when the learners experience an event through a multimedia simulation. Multimedia technology empowers the educational process by means of increased interaction between teachers and the students. Apart from the fact that multimedia can provide educators and students with endless possibilities of quality teaching and learning, taking vital considerations of the pedagogical strengths and limitations of Multimedia, it can be used to its fullest potency, and reach the eminence of 'New Educational Technology tool'.

A comprehensive numerical modelling and investigation has been carried out to analyse the effect of wind loads on various solar array mounting frame structures using ANSYS 18 Workbench (Mechanical). Extensive damages of solar arrays and mounting frames have been reported the world over due to high winds. In this study, 6 array mounting frames types has been considered and subjected to 55m/s basic wind for Indian Wind Zone VI. Solar arrays considered of dimension 6mx4m consisting 12 PV panels each of size 1mx2m, with panel tilt angle varied from 10° to 50° degrees. Wind loads subjected to panels in solar array were considered as normal pressure force over top and bottom surfaces to simulate forward and backward wind direction. Maximum deformation and maximum stresses were determined using ANSYS Workbench and compared with various array mounting system arrangements for each case of panel tilt angle and subjected to both wind incidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
