Chosen practical example: 1. Load-limited design – wire ropes 2. Energy-limited design – spring in pegs 3. Deflection-limited design – paperclips 1. Load-limited design – wire ropes Wire ropes function as a tie. Hence the constraint is to withstand a certain tensile stress before failing by fracture. σ_f=(CK_1c)/√(πa_c ) If the objective to maximize the allowable stress‚ then‚ the material indices is simply M=K_1c CES (Cambridge Engineering Selector) is utilized to plot

Practical Book Review of Petersen Text Lori Edwards Azuru Liberty University Summary James Petersen (2007) illustrates an innovative way of communicating in the book‚ Why Don’t We Listen Better? Communicating and Connecting in Relationships. This book is divided into five sections. In part one Petersen (2007) discusses the “Flat-Brain Theory of Emotions” (p. 10-11). This is his way of explaining what occurs when one is overcome with emotions‚ and can no longer communicate with

Some practical ideas for sustaining motivation 1 Experiment‚ take risks. Vary the kinds of things you do in the classroom. See what different students respond to best. For example‚ try short stories‚ films‚ classroom drama‚ songs‚ projects‚ grammar exercises‚ dictations‚… 2 Choose ‘larger’ tasks. Chose tasks that give students more ‘psychological space’ to plan their own work‚ set their own pace‚ make their own decisions about how and what they do. For example‚ process writing and simulations

A Practical Guide to Combating Products & Services Summary: This article revolves around the concept of hybrid solutions i.e.‚ combining products and services into innovative offerings to attract more customers and provide superior value to them. The article identifies two basic characteristics of any offering- complementarity (when used together) and independence (used separately) based on which four types of hybrid offerings emerge. These are as follows: i. Flexible Bundle: These bundles
