Lecture
This lecture covers the concepts of stationary creep and its influence on materials under stress, the relationship between applied stress and time to rupture, and the properties of different materials such as polymers, ceramics, and metals. It also delves into the selection criteria for materials based on rigidity and density. Additionally, the lecture explores the magnetic properties of ferromagnetics, including hysteresis curves, saturation magnetization, and remanent magnetization. The discussion extends to Miller's direction and plan indices in crystallography, with exercises on compact stacking and visualization of crystallographic planes.
