Using experience of many years teaching mechanics of materials, we have been continuously trying to find easier methods to help the students get a better understanding of fundamental concepts. This effort and investigation has led to innovative and simple approaches to prove the equations much easier than the existing ones and also to clarify complicated concept. In this paper, we are offering our innovative proof for elastic flexure formulas as well as an interesting model for the moment sign convention in the cross section of a beam. In this method, considering a portion of a beam under pure bending and obtaining the stress distribution in the cross section and applying the balance of the considered portion, we prove the Elastic Flexure Formulas much easier than the existing methods. Emphasizing on deeper understanding, some notes and a new model are offered during this proof.展开更多

The impact of Music education for college students is also reflected as follow： to enable students to cultivate the art of perceptual knowledge, this ability is an art feeling, to help students better understand the artistic charm, to strengthen their own requirements and strive for a more noble art. It is necessary for college music major to have Performance capacity, Teaching ability, Management quality and Innovation capacity, referred to as ＂PTMI＂ complex talent. This article makes an analysis on that training goal of college music majors should be shifted toward ＂PTMI＂ complex talent.展开更多
