Krikorian‚ Noah Marks‚ Ann Murray Report by Ryan Carmichael and Anne Krikorian E6 Laboratory Report – Submitted 12 May 2008 Department of Engineering‚ Swarthmore College Abstract: In this laboratory‚ we determined six different values for the Elastic Flexural Modulus of a 4-by10 (100” x 3.50” x 9.46”) Parallam wood-composite test beam. To accomplish this‚ we loaded the beam at 1/3 span with 1200 psi in five load increments in both the upright (9.46 inch side vertical) and flat (9.46 inch side

ratio of the stress applied to a body to the strain those results in the body in response to it. The modulus of elasticity of a material is a measure of its stiffness and for most materials remains constant over a range of stress. . Material | Elastic Modulus | | MPa | psi | Steel | 200‚000 | 30‚000‚000 | Poisson ratio It is the negative ratio of transverse to axial strain. In fact‚ when a sample object is stretched (or squeezed)‚ to an extension (or contraction) in the direction of the

some version of the following: “In the event of a change in cabin pressure‚ panels above your head will open revealing oxygen masks. Pull the mask down toward you to activate the flow of oxygen. Cover your nose and mouth with the mask. Place the elastic band around your head and continue to breathe normally. Remember to secure your own mask before assisting others.” That is how I look at life. In fact‚ because I have attended to myself and have prepared for my future job since I have been a college

Christmas‚ few people stop to think how it originated. Started as a pagan holiday during the time of Romans‚ it developed in to a Christian celebration dedicated for Christ. People in different age groups‚ both kids and adults‚ enjoy the season of Christmas. Christmas has been very big and an inspiring holiday for many families around the world for many centuries. Packed with busy shoppers‚ jingle bells‚ colorful lights and Santa Claus‚ Christmas is thought by many people to be "the most wonderful

2 both give methods of calculating the buckling stress in a strut. Euler equation: - Eq.2.1 Rankine Gordon:- Eq.2.2 Fig.2.1 shows a perfect pin-ended strut. This strut is assumed to undergo only axial loading and will remain in its elastic range prior to the critical load being reached. Deflection will only occur when the critical load is reached. Any deflections prior to this load are maintained inside the structure. Fig.2.1 a) Perfect pin-ended strut b) Deflection due

INTRODUCTION During collisions involving two bodies‚ equal and opposite forces are set up between them. These impact forces influence the subsequent motion of the bodies. Momentum of the system (consisting of both bodies) is preserved if both bodies are free to move in space. This is because there is no external forces act on the system. The forces acting between the bodies during the small interval of time when they are in contact cause changes in the velocities of each separate body. An

Samarpan Rai 30/11/012 Physics HL Investigation on Young Modulus Young’s modulus‚ also known as the tensile modulus‚ is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. Young’s modulus is named after Thomas Young‚ the 19th century British scientist. It is a very important concept that categorizes metals on basis of their elasticity. In the last lab‚ we were asked to find out the Young Modulus of two wires: Copper and Steel. I worked on Copper

It can be used unfairly which makes it a disadvantage to other partys which is why there are laws in place to limit the use of clauses and to make it fair.

Santa Clause Tradition Christmas is a tradition for a majority of families across the United States. For my family it is a time for us to come together and appreciate the love of one another. Everyone gathered around a warm fire‚ drinking hot cocoa‚ singing Christmas carols‚ watching the Christmas lights glisten off the frosted ground‚ and opening presents at the break of dawn. So why do we bring a fictional character into this simply beautiful medley? Santa Clause shouldn’t be what families focus
