California State University, Long Beach Mechanical and Aerospace Engineering Department MAE 361: Materials and Properties Laboratory Torsion Test of Metals and Polymers Date: October 29, 2013 Submitted To: Dr. Parvin Shariat Submitted By: Ryan Kim D. Lim - 008142015 Steven Reid - 007777066 Thomas Leininger- 008403601 Marco Evangelista – 007774076 Objective: The objective of this experiment is to determine the shear stress, shear strain, and shear modulus of elasticity of solid

does this because it has a large surface area and will catch more air. Since the parachute is slowing the egg down then the acceleration is also decreasing. Newton’s second law states that acceleration times mass equals force. So if the parachute decreases the acceleration the force on the egg will decrease making it less likely to break. Another change we had made was using lighter materials to decrease mass. If we decrease the mass the momentum that egg will have will also lessen because

A P_1 Force due to P_1 on area A acting up = P_1 A Force due P_2 on area A acting down = P_2 A Force due to the weight of the element =mg= ρA(z_2- z_1 )g Since the fluid is at rest, there can be no shear forces and hence no vertical forces on the side of element due to surrounding fluid. Considering upward as positive, sum of all forces = 0, We have P_1 A-P_2 A - ρA(z_2- z_1 )g=0 Or P_2- P_1= - ρ(z_2- z_1 )g

that involves overcoming many forces. Bulls will try just about anything to get a rider off their back. This includes raring, kicking, spinning, jumping, belly rolls, and some unintended moves such as stumbling and falling down. All the moves produce some sort of force the rider has to overcome. Fortunately ... in great shape. Much energy is spent in the course of a bull ride. The energy is equal to the force applied times the distance traveled. The forces are great and as fast as a bull

Introduction This investigation is designed to utilise the formulas learnt in trigonometry, to investigation the heights and distance of trees, buildings and roads. These formulas were based off and included Sinθ=opposite/hypotenuse Cosθ=adjecent/hypotenuse Tanθ=opposite/adjecent As a real world application to the formulas at use in terms of the Trigonometry Direct Investigation and the topic currently used, Trigonometry, it can lead to things such as measuring the lengths of tall objects such as

When Balloons Explode Purpose and Objectives The purpose of the Balloon Therapy Activity is to engage the client to share information in a fun and interactive manner. The client will also have the opportunity to express their emotions in a healthy manner; anger is the emotion that this activity focuses on. This activity will provide the family with a greater insight on how holding anger inside can lead to problems. Moreover, this activity will help the family/client gain new coping techniques to

Baker & Newton (2004) postulate that balance between the agonist and antagonist muscle groups is essential for improving performance and injury prevention purposes. Negrete et al. (2013) examined the upper body push and pull strength ratio in 180 recreationally active males and females adults using timed push-ups and timed modified pull-ups. The test protocols consisted of 3 maximal sets of 15 seconds for both push-ups and modified pull-ups. The average of the 3 maximal sets was calculated and the

Would you dedicate over 40 hours a week to something without getting paid? Well, there are many people and even sports fans alike that believe college athletes do not deserve to be paid; but they do not realize everything they are going through. These kids are not only athletes but students as well. They not only dedicate over 40 hours a week to their sport, they have to maintain their grades and attend all of their classes. They must work harder to get all of their work done and reach their goals

basically “a surface of which one end or side is at a higher level than another; a rising or falling surface.” After a roller coaster climbs up the first big hill using a lift or cable to get to the top, the way down is controlled by gravity, or “a force of attraction between masses.” Then, the stored energy is released as kinetic energy, which is “the mechanical energy that something has while being in motion,” this will get the rollercoaster up the next hill. As the cart travels up and down the rest

Last year on Christmas Eve my co-worker brought his 7-year-old son into the office for the half day. H came with a sack full of dinosaurs and drew me a picture of a T-Rex (which still hangs on my cubby wall). This year H came with his Star Wars coloring pens and I now have R2D2 hanging next to Rex. H and his dad chided me for not knowing who all the latest Star Wars characters are and all the hype around the Christmas release of Rogue 1. So I dug up the flash drive another co-worker gave me last
