In order to gauge any effects the slat system, with various weights, may have on the shock wave, several baseline tests were run. These tests did not have the device installed in order to record and understand the basic performance of a shock wave coming straight from the shock tube. To record the pressure profile of the wave within the expansion section, GageScope was used. A trigger was set to detect a rapid rise in voltage from the pressure transducer, and the program would record 1ms before and 10ms after the trigger. The initial baseline test can be seen in Figure X below. For a greater focus on the effects of the device on the shock wave, all charts for comparison has been narrowed to 2ms after the trigger. The two significant runs showing the pressure profile of the shock wave are shown in Figures X & Y.

These figures show that the pressure rises from atmospheric (0mV) to peak pressure in a rise time of around 0.000039 seconds, or 39 µs. This is representative of a shock wave due to a nearly instantaneous rise time. Baseline test 1 burst at 51 psi while baseline test 2 burst at 53 psi.
The initial design did not perform effectively at achieving its intended functions when installed and tested with the shock tube. Upon firing the shock tube, the slats would not rotate. Several firings were attempted, all resulting in no rotation of the rods. The

Both Louis XIV and Peter the Great were famous rulers of the late 17th- early 18th Centuries. Both took the throne at a young age and both had many strengths and weaknesses. Louis XIV had many strengths during his reign as ruler of France. Appointing Jean Baptiste Colbert as his minister of finance made some of his greatest strengths and accomplishments. One strength was that of mercantilism, which is an economic theory under which a country increases its wealth by exporting more goods than it imports. By accomplishing this, Louis XIV made himself and France very wealthy. More wealth was made when a balance of trade brought more gold and silver into France. A high tax was
This report aims to describe the experiment performed to investigate the stiffness of a channel section, and in particular calculate the flexural rigidity (EI) of the beam by two different sets of calculations based on the results gained in the experiment. The EI of an object is used
I am going to argue that Weirob is wrong to claim that the survivor to the Julia-Mary case is Mary. (20 words)
In this experiment we tested the effect of change in arm length of the Trebuchet on the distance traveled of the projectile. We wanted to do this experiment due to our interests in engineering and our interests in the medieval era siege weaponry. We started by researching different types of Trebuchets and decided to go with the most modular and modern version. We decided to build a floating arm Trebuchet which uses the counterweight as the fulcrum. This allowed us to easily exchange the arms for testing. We built the Trebuchet using long 5.08cm x 10.16cm (2in x 4in) pieces of wood, four 4.54kg (10lb) weights, a single 1.27cm (1/2in) x 1.22m (4ft) piece of rebar, and a pouch made of paracord and duct tap. We tested this by building a Trebuchet
CONSTRUCTED RESPONSE 1. Do you ever want to have children in the future? If so, China would not be the place to build a big family. In China, there was a policy, established in 1980, called the one-child policy. Their country was facing problems of overpopulation, and limited Chinese couples to having one child.
As a trainer, teacher and assessor my roles are many and varied. As part of my day to day work I may not only deliver lessons but also carry out theory assessments, practical assessments and sometimes interviews. I may have to motivate and liaise as well as guide and assess. I will have to keep records and be a subject specialist as well as liaise internally and impart information and advice sometimes on a personal level. The first impact I play regarding my role is either interviewing possible candidates or meeting and greeting them on the first day of their course. Meeting potential apprentices/apprentices on their first day induction requires me to make a good

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.
