The material presented herein has been compiled largely from the data of NACA reports and technical publications. This book was prepared as a source of data and procedure for use in the sizing and design of both airframe and space vehicle structures and is the only book that has been widely used by the Aerospace Industry to date. It was originally published in 1965, and was revised in 1973. Bruhn is one of the most useful Aerospace Industry and University text books ever written with the emphasis on practical application with input from both material strength and hands-on experience. 'Analysis and Design of Flight Vehicle Structures'Īnalysis and Design of Flight Vehicle Structures by E.F. In all cases, basic ideas and equations are presented along with sample problems that illustrate the major ideas and provide practice on expected exam questions.This document 'Analysis and Design of Flight Vehicle Structures - Chapter A3: Properties of Sections - Centroids, Moments of Inertia, etc. These are moments of inertia, centroids, and polar moments of inertia of simple and composite objects. Finally, we analyze the geometrical properties of lines, areas, and volumes that are important in statics and mechanics of materials. The concept and major characteristics of trusses are discussed, especially simple trusses, and we show how to analyze them by the method of joints and the method of sections. Then how to analyze pulleys and compute static friction forces and solve problems involving friction. We show how to draw a meaningful free body diagram with different types of supports. We discuss the concept of equilibrium of a rigid body and the categories of equilibrium in two dimensions. Then the meaning and computation of moments and couples. We discuss the main characteristics of vectors and how to manipulate them. Then we consider systems of forces and how to compute their resultants. We first discuss Newton’s laws and basic concepts of what is a force, vectors, and the dimensions and units involved. This module reviews the principles of statics: Forces and moments on rigid bodies that are in equilibrium.
