Critical Analysis Of Load Distribution On a scissor Jack Gabriel Chong‚ Paul Stegner‚ Chris Yorgey Department of Physics and Engineering Elizabethtown College‚ Elizabethtown‚ PA Email: chongg@etown.edu‚ stegnerp@etown.edu‚ yorgeyc@etown.edu INTRODUCTION In this discussion we will introduce our critical analysis of the load distribution on a scissor jack. It has been specified that this jack is to hold a load of 100 lbs on the top plate‚ with the jack height set to 7 inches.

26/09/11 The Falling Man The Falling Man is a photograph of a man who is falling from the North tower of the World Trade Center during the crisis of the 11th September‚ taken by a photographer called Richard Drew. This picture in particularly was chosen to appear in the newspapers of the world‚ it was seen only once in the New York Times but was then removed due too much criticism. This photo caused a lot of arguments in terms of the U.S. newspaper industries; this was because of the way the people

(T1R + W1E)/ mass | Bottom of Form Block 1 (4 kg) is located on the surface of a table. A hand pushes horizontally to the right on block 1 with a normal force of 16 N. On a sheet of paper‚ draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram‚ enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component. FORCES on BLOCK 1 Weight force on block 1

Abstract Static equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating

Build Water Rockets Explain how they work and ask the students which of Newton’s laws apply to them. You should talk about what forces are acting on the water rocket to make it move (talk conceptually about the idea of a free body diagram). You should have the force from the ejected propellant acting upwards‚ and the weight and air resistance acting downwards. Talk about how each law applies to the physics of the water rocket. Try to have the students identify which

“The Falling Man” Looking at this picture‚ emotions rush through your body making you remember the terrible event that happened on Tuesday‚ September 11‚ 2001. The story behind this picture has to do with the most horrific day in history; the day terrorists crashed two planes in the towers of the World Trade Center. Fifteen seconds past 9:41 a.m. on September 11‚ 2001‚ Richard Drew took the picture of the now world known famous‚ “The Falling Man.” He jumped head first‚ like an arrow shooting

Falling in Love Everyone has been falling in love at one point of his life. Not only grownups‚ but also teenagers have felt this feeling. Falling in love is very difficult it’s hard to characterize because everyone occasionally has different types of feelings. For example‚ humans can love other people‚ creatures‚ or material objects‚ but it is all the same thing: love. Giving into their emotions and psychological temptations causes them to fall in love. That is why everyone

Falling Water Falling Water’s plans all came about when the architect‚ Frank Lloyd Wright was born‚ Jun 8‚ 1867. Frank was born in Richland Center‚ Wisconsin. Wright designed Fallingwater in 1935. At his death in 1959‚ he had built more than 400 buildings. Wright’s most famous house was designed and built for the Pittsburgh Kaufman family‚ for a weekend retreat. The natural wonder Fallingwater is recognized as architect Frank Lloyd Wright’s most acclaimed and famous works. In 1991‚ a poll
