The document contains formulas for calculating geometric properties of various 3D solids. It lists direct and inverse formulas for calculating the area, total area, volume, and dimensions of solids such as parallelepipeds, cubes, prisms, pyramids, cylinders, cones, spheres, and regular polyhedra. The formulas relate properties like base area, total area, volume, height, length of sides, radius, and circumferences.
This document discusses stress, strain, elasticity, and material properties related to mechanical deformation. It defines stress as force over area, strain as the ratio of deformation to original length, and introduces Hooke's law which states that stress is proportional to strain for small deformations. Young's modulus is defined as the ratio of stress to strain, providing a measure of material stiffness. Examples are given of the Young's modulus for various common materials like rubber, wood, bone, and steel. Shear stress and modulus are also defined. The document compares tensile and compressive strengths of materials and discusses how arches effectively use compression strengths.

1) The documents provide examples of solving for forces in truss members by using free body diagrams and equilibrium equations.
2) The solutions involve drawing FBDs of the trusses or sections of trusses, then writing the ΣF and ΣM equations and solving the systems of equations.
3) The determined forces are then identified as either tension or compression forces in the members.
This document discusses properties of polygons and their areas. It provides formulas to calculate the areas of trapezoids, rhombuses, and similar polygons. It also outlines principles of equal areas, such as parallelograms and triangles having equal areas if they have congruent bases and altitudes. Several problems are solved as examples, such as finding missing lengths or areas of trapezoids, rhombuses, and proving polygons have equal areas.

The document discusses mechanics of solid deflection in beams. It provides relationships between bending moment and curvature, as well as sign conventions for shear force, bending moment, slope and deflection. It then analyzes simply supported beams with central point loads and uniform distributed loads. Equations are derived for slope, deflection and bending moment at any section. Cantilevers with point loads and uniform distributed loads are also analyzed. Macaulay's method, a versatile technique for determining slope and deflection in beams under various loading conditions, is introduced. Examples applying the concepts to specific beam problems are included.
Chapter 4-internal loadings developed in structural membersISET NABEUL
This document provides examples and explanations for determining internal forces like shear force and bending moment in structural members like beams and frames. It begins by introducing sign conventions and the procedure for analysis, which involves determining support reactions, drawing free body diagrams, and using equilibrium equations. Numerous step-by-step examples are then provided to demonstrate how to calculate and graph shear force and bending moment diagrams for beams and frames with different loading and support conditions.
Burberry aims to be the first fully digital brand by creating an immersive "Experience" across all digital platforms and devices. They strive for total consistency in brand messaging. Over 60% of Burberry's marketing budget is spent on digital initiatives. Burberry uses each digital channel appropriately to engage consumers and express the brand. They create always-on, relevant content through collaboration, experimentation and a consistent creative approach. Burberry's digital success demonstrates how to build a cohesive multi-platform strategy that immerses consumers in a luxury lifestyle experience.
Burberry has undergone a digital transformation to focus on its brand and connect with younger global consumers. CEO Angela Ahrendts and CCO Christopher Bailey envisioned Burberry becoming the world's first fully digital luxury company. They developed a rich digital culture across Burberry's marketing, products, retail experiences, and internal operations. All parts of the business are now linked to deliver a seamless brand experience for customers anytime, anywhere. Through innovation and partnerships, Burberry has established itself as a leader in digital luxury and seen exceptional sales growth compared to industry peers.
The first truly digital luxury brand: why Burberry gets it?
With the launch of The Art of the trench, Burberry certainly became the first truly digital luxury brand. The first luxury brand to really understand and adopt digital behaviours to conceive and support its brand online communications. There are many reasons why it became a clear success and digital is certainly one piece of a bigger picture.

This document provides an overview of Burberry's strategic development from the recent past to 2011. It discusses Burberry's introduction in the late 19th century as a trench coat manufacturer and its popularity during World War I. In the 1980s and 1990s, Burberry's brand popularity waned but it underwent a transformation starting in the mid-1990s under new leadership to focus on higher-margin accessories and position itself as a global luxury brand. The document also examines Burberry's business model, leadership culture, and the strategies it deployed including leveraging its brand, expanding into new product categories and markets, and pursuing operational excellence.
Limitare la spesa energetica per la conduzione degli impianti termotecnici al servizio degli edifici, risulta conveniente isolare maggiormente l’involucro edilizio (pareti esterne, soffitti, infissi con bassa trasmittanza termica). In questa maniera diminuiscono gli sprechi energetici: l’energia occorrente al mantenimento delle condizioni di confort indoor non viene dissipata all’esterno.
