Personal Write up For this lab, bottle rockets were to be made by the materials of duct tape, a tennis ball, cardboard, and a liter bottle. Using water as fuel, the rocket that is constructed was launched at the pressure of eighty PSI. The objective of this lab was to build the rocket efficient enough to launch at a range of two hundred to three hundred feet by calculating different variables. The independent variables of this lab were the shape and mass of the rocket, the angle degree the…

Lab 1: Flow Visualization Jintark Kim Purdue University ME309 lab Section 009 Abstract The purpose of this experiment is to visualize and analyze the flow patterns formed by objects in different conditions: cylinders in different diameter at different flow rate, and airfoils with different angle of attack at a constant flow rate. Properties of water at measured temperature and flow conditions for each trial were used to compute the Reynolds number. Red-dye ejector was used to traces the…

Statement of Purpose My grandfather and father were physicians and as a consequence, there was always an influence on me to be the next generation physician. We had a family garage, where my father and I used to repair our old-modelled motorcycle together with various other broken domiciliary machines and passed hours there. I was fascinated and excited by all these equipment and the idea of being an engineer in the future had peeped through my mind several times. But those could never surpass…

I. INTRODUCTION (OVERVIEW) Before the pilot use the real cockpit of the real aeroplane, they need to train their skill by using a system called flight simulator. Flight simulator is the system that looks like the real cockpit of the airplane but the truth is, it’s only a fake cockpit that had been designed special for the pilot training. The simulator were designed to help the pilot to test or train their skill in handling the cockpit in every situation that they might face during handling…

The four forces of flight are the main reason why planes fly and how they are able to glide through the air majestically. Each force of flight helps to guide the airplane to its destination by helping it withstand gravity and pressure. Lift is one of the four forces, lift is an upward force that is created by the movement of air above and below an airplane wing. Lift helps balance out the weight of the plane for it to be able to withstand gravity. Lift's air flows faster above the wing and…

This experiment was done to see what variables (weight, wind, friction etc.) affected the apogee of the rocket. The class did this by recording everyone's rocket weight and compared them to the apogee's after they had been launched. Due to different variables, the apogee might be affected in a variety of ways, one being the weather. After the class found all of the data, it was compared and analyzed for any patterns. The rocket had different forces acting upon it during the flight stages. The…

Procedures How was the experiment carried out to answer the problem? Day 1 - Determining Flight Factors On the first day we discussed as a class what variables could affect the flight path of the balloon. This list included anything from the placement of the balloon in the slingshot to an innocent bird flying by while the balloon is in the air. Each factor was then sorted into a category of either a control variable or an act of god. From the list of control factors, we selected the mass of…

1. Flights of Fancy 2. “It’s really pretty straightforward: flight is freedom.” (136) 3. Foster explained in a story about people with “wings” and those “wings” provide freedom. However, with freedom comes the ones who abuse it. As you can see, the title of the chapter is Flights of Fancy which can explain the stereotypical snotty rich kid everyone hates. This is because rich people are fancy and rich people are very free, but can abuse their freedom to make the wings dirty, as Foster explained.…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…

Determining the effect of the mass on the drop time of a parachute Introduction and hypothesis The drop time of a parachute is dependent on multiple factors. Apart from mass, there is the obvious height, area of the parachute and other external factors such as wind. Mass is one of the main effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down…
