Concept explainers
(a)
To graph: the model of the given cam.
(a)
Answer to Problem 48E
The graph is an ellipse.
Explanation of Solution
Given:
Concept used:
The graph of the equation can plot using Desmos graphing calculator.
Calculation:
Consider the cam in a punch press shaped like an ellipse, with the equation:
The camshaft goes through the focus on the positive axis.
To graph the model of the cam as:
Hence, the graph is an ellipse.
(b)
To find: Theequation of the model when the camshaft is at the origin.
(b)
Answer to Problem 48E
The equation of the translates the model is
Explanation of Solution
Given:
Concept used:
The equation of ellipse:
Calculation:
the same picture in the other graphing calculator is:
Hence, The equation of the translates the model is
(c)
To find:the equation of the model in part
(c)
Answer to Problem 48E
Explanation of Solution
Given:
Concept used:
