be examining how the kinetic friction coefficient is altered by changing the mass‚ surface area‚ speed‚ and material contacting each other. In order to find this value‚ we will be using a pulley apparatus that will allow us to measure the average velocity and manipulate Newton’s Second Law of Motion to find the kinetic friction coefficient. Based on contacting each other. Procedures First we began by leveling the track using the bulls-eye leveler. Then we connected the pulley to the interface device

CVEN 3031: BASE MODEL DEVELOPMENT The base model development involves the following stages described in the RMS Traffic modelling guidelines: http://www.rta.nsw.gov.au/doingbusinesswithus/downloads/technicalmanuals/modellingguidelines.pdf The following sections relate these concepts with the requirements of the assignment. Model Verification Verification is achieved by looking at the geometry of the network. It is important to ensure that the model network closely resembles what is observed

VIBRATION MEASUREMENT In some practical situations‚ it might be difficult to develop a mathematical model of the system and predict its vibration characteristics through an analytical study. In such cases‚ we can use experimental methods to measure the vibration response of the system to a known input. This helps in identifying the system in terms of its mass‚ stiffness‚ and damping. In practice the measurement of vibration becomes necessary for the following reasons: 1. The increasing demands

That is to say‚ each point plotted on the graph (parabola) will be a measurement to this effect: Suppose a ball is thrown into the sky at a velocity of 64ft/sec from an initial height of 100ft. We would set the quadratic equation as (s)0=-gt^2+v0t+h0 and substitue values for gravity‚ velocity‚ and initial height to equal 0=-16t^2+64t+100. If we want to find out after how many seconds the ball will land‚ we can leave the equation set to zero and solve for t‚ using

VicosÓ¨Ît). When broken down Vi cosÓ¨Ît is the initial velocity of the object in the x axis multiplied by how long it has been traveling at that speed equals your displacement in the x axis. The other dimension is the vertical witch is usually called height (h=VisinÓ¨Ît+1/2at^2) witch is similar to the horizontal motion except we have to account for the force of gravity. When we brake down the equation we see the height is equal to the initial velocity (VisinÓ¨Ît) of the object in the y axis plus half

What is Isokinetic Isokinetic (n) is a term used to describe a type of movement or exercise. Isokinetic or Isokinetics Definition: The word isokinetic is most commonly used in sports science and medicine. In these settings isokinetic defines a type of exercise or movement. Isokinetic movement is actually the opposite of isotonic movement which is probably the easiest way to think of it. Isotonic movement is the most common type of movement we human beings perform: Isotonic movement: In almost

(a) From our equations of motion‚ the horizontal velocity is constant. This gives us the flight time for any horizontal distance starting with initial x velocity vicosθ. Thus the vertical height of gx 2 the trajectory is given as y = x tan θi – . With x = 36.0 m‚ vi = 20.0 m/s‚ and θ = 2v 2i cos2 θi 53.0°‚ we find y = (36.0 m)(tan 53.0°) – (9.80 m/s2)(36
