MEM23061A Test Mechanical Engineering Materials Lab. BEAM BENDING The bending of beams is one of the most important types of stress in engineering. Bending is more likely to be a critical stress than other types of stress - like tension‚ compression etc. In this laboratory‚ we will be determining the Modulus of Elasticity E (also called Young’s Modulus) of the various materials and using Solid Edge to determine the Second Moment of Area for the different cross-sections.

Introduction: Capture and recapture is a method to observe animals‚ give information on survival‚ recruitment‚ and size of the population. You capture the animals and mark them and release them. Mark and release repeatedly. Objective: The purpose of this experiment was to analyze the amount of marked beans of the beans we would catch. Hypothesis: If the number of marked beans represents the number of the mocking jays in the forest and the unmarked beans are the food supply then the mocking jays population

Objective: One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Purpose: We are doing this experiment to find the best ratio of potassium nitrate to powdered sugar for a model rocket motor that will create the most thrust. We are also testing if adding fins will affect the flight distance of the rocket. Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson‚ who has experimented with the best ratio of powdered sugar to potassium nitrate‚ has stated that “The 1 to 3 ratio is best for creating the most amount of thrust

tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds (81 degrees)‚ preformed the experiment for two more

Abstract: This experiment will determine if jumping beans are alive. We tested two groups. Group A and B. We put them in two different areas. Three beans were put in a lit area and three were put in a shaded area. It was found that if the depending on how lit the area is the more movement we saw from the jumping bean. Therefore it can be said that jumping beans are alive and respond to stimuli. Introduction: This Experiment “ Mexican Jumping Beans” focuses on how jumping beans respond to different
