Chapter 4 Analysis of Structure Introduction Structure connected system of members designed to support loads safely or to transfer forces effectively Analysis of structures involves analyzing the equilibrium of the entire structure part of the structure or an individual member. Fig Buoyancy The Buoyancy is an upward force exerted by the flui d on the body when the body is immersed in a fluid or floating on a fluid This upward force is equal to the weight of the fluid displaced by the body CENTER OF BUOYANCY a Floating Body Presented by Brittany Johnson.
