Science > Physics > Heat Transfer > Conduction Heat always gets transferred from the body and higher temperature to a body at lower temperature heat transfer can take place in three ways a) Conduction b) Convection and c) Radiation. In this article, we shall study the heat transfer by the conduction. Conduction: If one end […]
Science > Physics > Heat Transfer > Convection and Radiation In this article, we shall study different modes of heat transfer. Convection: Convection is a mode of heat transfer through a material medium in which heat energy is carried from one place to another by actual motion “migration” of heated matter. Consider a beaker containing […]
Science > Physics > Elasticity > Concept of Strain Energy In this article, we shall study, work done in stretching wire and the concept of strain energy. Work done in Stretching a Wire: Consider a wire of length ‘L’ and area of cross-section ‘A’ be fixed at one end and stretched by suspending a load […]
