problem 261 A steel rod with a cross-sectional area of 0.25 in2 is stretched between two fixed points. The tensile load at 70°F is 1200 lb. What will be the stress at 0°F? At what temperature will the stress be zero? Assume α = 6.5 × 10-6 in/(in·°F) and E = 29 × 106 psi. Solution 261 For the stress at 0°C: answer For the temperature that causes zero stress: answer problem 262 A steel rod is stretched between two rigid walls and carries a tensile load of 5000 N at 20°C.

Test A. Introduction As shown by the Griffith criterion‚ tensile strength of brittle materials is theoretical 1/8 of the compressive strength. Typically‚ tensile strength of rock materials is about 1/10 to 1/8 of the compressive strength. Hence‚ rock fails easily under tension. In design‚ rock should be subjected to minimum tensile stress. Several methods are commonly used to test the tensile strength of rocks: 1. Direct tensile test: Metal caps are cemented to the

The strengths approach is a method of working with people that focuses on developing their natural abilities and capabilities. It allows people to identify and build on their strengths so that they can reach their goals‚ and retain or regain independence in their daily lives (McCashen‚ 2005). Strengths-based approach is built on the premise that the normal human development process is towards healthy growth and fulfilment‚ and that everyone has strengths that will aid them in this process (McCashen

This book review is on Strengths Finder 2.0. Written by Tom Rath‚ this book follows and elaborates on Donald Clifton’s Strength Finder assessment created in 1998. Strength Finder 2.0 looks to dispel the outdated belief that only weaknesses need to be improved upon. The textbook Psychology Applied to Work describes this concept as positive psychology‚ "The aim of positive psychology is to shift the emphasis away from what is wrong with people to what is right with people" (Muchinsky & Culberson

What Strength Can Be “Having the power to move heavy weights or perform other physically demanding tasks” is defined as being strong (Oxford Dictionary). That is exactly what most people think of when they hear the word strong. To some‚ strength is only in physical form‚ but for others it comes in emotions and mental stability. When I hear the word my mind automatically thinks about mental capability and performance. I think of three ways to define the meaning of strong‚ physically‚ emotionally

One of the strengths of this test is that it includes a very detailed and easy to follow fitness classification chart. In order to find your classification‚ all you have to do is find your age and sex. After finding which chart relates to you based on your age and sex‚ you can easily identify which category you fit into. Not only that‚ but it doesn’t require much equipment. Any person that knows how to swim at least one stroke safely for 12 minutes could take this test. Another strength is that it
