Question
You are working as a Junior Engineer for a small motor racing team. You have been given a proposed mathematical model to calculate the velocity
You are working as a Junior Engineer for a small motor racing team. You have been given a proposed mathematical model to calculate the velocity of a car accelerating from rest in a straight line.
The equation is: v(t)=A(1-e^t/t_maxspeed )
v(t) is the instantaneous velocity of the car(m / s)
t is the time in seconds
t_maxspeed is the time to reach the maximum speed in seconds
A is a constant.
The Team Manager has asked you to carry out an analysis of the model and produce a written report. As part of the analysis you have been given some data on a known model.
Data:
Car Model = Bugatti Veyron t(0-28m/s)(s) = 2.5
t(400m) = 9.75
t_maxspeed(s) = 8.0
However, the time taken to reach the steady state value (maximum speed) is approximately 5 time constants, so the model as it stands cannot work accurately. A modified model recognising this issue would be to change it to
: v =A(1-e^-5t/t_maxspeed)
Produce a report that contains written descriptions, analysis and mathematics that shows how calculus can be used to solve an engineering problem. Your Answer must include :
• methods to analyse the given engineering problem
• a valid proposal for solving the problem and present it
• Apply calculus methods to produce answers for each of the elements
• Bring the elements together in a formal presentation(most important)
Your Question:
In your proposal you need to outline the problem and the methods needed to solve it. You need to include how to:
1. Identify the:
● units of the coefficient A
● physical meaning of A
● velocity of the car at t = 0
● asymptote of this function as t → ∞?
2. Sketch a graph of velocity vs. time.
3. Derive an equation x(t) for the instantaneous position of the car as a function of time. Identify the
● value x when t = 0 s
● asymptote of this function as t → ∞
4. Sketch a graph of position vs. time.
5. Derive an equation for the instantaneous acceleration of the car as a function of time. Identify the:
● acceleration of the car at t = 0 s
● asymptote of this function as t → ∞
6. Sketch a graph of acceleration vs. time.
7. Apply your mathematical models to your allocated car.
Use the given data for the 0 – 28 m/s and 400m times to calculate the:
● value of the coefficient A
● maximum velocity
● maximum acceleration.
Additional information: To achieve the starting marking criteria you must show that you are able to: Solve accurately, using calculus methods and a mathematical model, a given engineering problem
From Question 1 to 7
Personal Added Information: Please explain everything step by step as I have to present this with some other car model values, in terms of a presentation, I can use any notes, so please explain very clearly in each step you go.
