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

An air Compressor is one of the major energy consuming utilities in any industrial operation and are mainly classified in two types. The classification is based on their construction and operation features. The two main classification of Air Compressor are: 01) Positive Displacement Type 02) Dynamic Type. You will find details of each type from below description. 01) Positive Displacement Type Air Compressor. Positive displacement types compressor are those‚ who mechanically displace

When something spins it undergoes “rotational motion”. When something spins around a single point it is called “circular motion”. B. We measure how fast something spins not in m/s (different points on the object are spinning at different velocities) but by measuring the angle described in a given time period. C. Angles can be measured in radians (rad) 1. The radian is the ratio of the arc length (s) to the radius (r) of a circle (insert fig. 7-1 here)

The reaction time is the amount of time required to sense astimulus‚ analyze its meaning‚ and respond. Acceleration is the rate of change of velocity. Velocity is speed with direction. Displacement is the moving of something from its place or position. Free fall acceleration is when there is no air resistance affecting an object. equation for reaction time: t= 2Δx g constant acceleration equation: Δx = v0 t+ 12 at 2 Velocity:

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

Find the average final velocity. Start with a ramp height of two workbooks. Release the steel ball from your chosen release point. When the ball leaves the end of the meter sticks‚ start the timer. When the ball reaches the 30 centimeter mark‚ stop the timer. Repeat for 5 trials for each height. If there is an error in the trial‚ do not use that trial‚ and redo that attempt. Enter all data in data table 1‚ then calculate the average final velocities. Find the average acceleration. Start

from the results of the marble’s average speed‚ it was slower when it was at the top of the ramp rather than towards the middle or the end. This is why the marble picks up speed as journeys down the ramp. As for acceleration‚ it is the rate at which velocity changes over time. An object accelerates when there is a change in speed‚ direction‚ or both. Because the marble gains speed as it travels down the ramp‚ it has acceleration. Although the marble only has a change in speed and not direction‚ we can

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
