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

Prac Report Problem: How does the increase mass affect acceleration and the force of the accelerating object? Purpose: The purpose of the practical is to find how mass affects acceleration and how it affects also the force of the accelerating body. To do this we are going to do the ticker tape experiment where an accelerating body pulls a tape through a consistent 50 dot per second ticker timer. The acceleration body in this experiment will be a small trolley pulled by a string that is pulled

Heart Dissection Practical Report. Introduction On the of July 2002‚ a sheep’s heart was examined by dissection. The heart is a muscle in all mammalian bodies that is used to pump blood and nutrients throughout the body. A sheep’s heart was used in this prac because like the human heart it has four chambers and is similar in size. Two of these chambers are receiving chambers called the left and right atrium. The other two are pumping chambers called the right and left ventricle. The reliability

ACI STRUCTURAL JOURNAL Title no. 106-S64 TECHNICAL PAPER A Practical Equation for Elastic Modulus of Concrete by Takafumi Noguchi‚ Fuminori Tomosawa‚ Kamran M. Nemati‚ Bernardino M. Chiaia‚ and Alessandro P. Fantilli Many empirical equations for predicting the modulus of elasticity as a function of compressive strength can be found in the current literature. They are obtained from experiments performed on a restricted number of concrete specimens subjected to uniaxial compression. Thus‚

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
