The resisting area is the shaded area along the perimeter and the shear force is equal to the punching force . answer Problem 116 As in Fig. 1-11c‚ a hole is to be punched out of a plate having a shearing strength of 40 ksi. The compressive stress in the punch is limited to 50 ksi. (a) Compute the maximum thickness of plate in which

Tensile Strength Report | Materials in Practice CP4088/CP8011 | By Clinton Chang | Synopsis This experiment is to find out the tensile strength of different plastic materials. The four plastic materials used are General Purpose Polystyrene (GPPS)‚ High Impact Polystyrene (HIPS)‚ High Density Polyethylene (HDPE) and Polypropylene (PP). By using three samples from each plastic material type‚ we are able to obtain the mean tensile strength‚ mean tensile modulus and mean yield strength of each

Taking the Strengths Quest assessment has been enlightening for me. Because of the assessment‚ I now know what core traits drive me and my personality. Now that I am conscious of these strengths‚ I can continue to use them to become a better leader. To be a great leader‚ one must know their strengths and play to them. My strengths are deliberative‚ intellection‚ harmony‚ competition‚ and input. I now know that these five strengths will guide me and my leadership philosophy. These five strengths can guide

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

It is actually pretty scary how accurately is depicts me through my strengths. My five strengths‚ in order‚ were context‚ learner‚ input‚ achiever‚ and intellection. While reading through the descriptions of my strengths list it was as if I was having Déjà vu. One of the strengths I was assigned was input. The description of input for me was‚ “craving to know more

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
