Section 13.6: Problem 9 (1 point) If a parametric surface given by $\mathbf{r}_1(u, v) = f(u, v)\mathbf{i} + g(u, v)\mathbf{j} + h(u, v)\mathbf{k}$ and $-4 \le u \le 4$, $-3 \le v \le 3$, has surface area equal to 7, what is the surface area of the parametric surface given by $\mathbf{r}_2(u, v) = 3\mathbf{r}_1(u, v)$ with $-4 \le u \le 4$, $-3 \le v \le 3$?

This question is in three parts, labelled (a), (b) and (c). A thin-sheet material is loaded in tension. As shown in the diagram below, the sheet has a notch on one side, oriented perpendicular to the tensile axis. a P, \Delta (a) Write a simple general equation which describes the changes in potential energy that might occur when the notch begins to extend (i.e. fracture begins) in response to the applied deadweight load. Enter your equation into the entry field provided below. There is no need to define the terms -- that will be done in part (b) of the question.

Create a class called Student with three PRIVATE instance variables, A String name, a String letterGrade and an int numGrade. The Student class will also have 6 instance methods which will allows us to get and set the values of the instance variable (Setters and Getters) and one instance method called studentinfo, displaying the students information. The names of the methods will simply be the names of the instance variables with set or get as a prefix, ie. setName, getName, setLetterGrade, getLetterGrade, setNumGrade, getNumGrade. The get methods should return the corresponding instance variable you are trying to return, so getName should simply return the instance variable name and its return type should be the same type of the instance variable. Set methods return nothing, take one parameter (the datatype should be the same type as the instance variable you are modifying) and simply set the value of the parameter as the the value of the corresponding instance variable. LE. setName("Sandra") should set the instance variable name to "Sandra". NOTE: The only setter that takes In no parameters is the setLetterGrade, this method will set the letter grade based on the number grade The set and get methods for letterGrade should be PRIVATE. All others should be public. In the setter for setLetterGrade, you will set the letter grade based on the value of the numGrade, if numGrade is between 100-88 set letter Grade to A, 88-76 B, 76-64 C, 64-52 D, below 52 F. The studentinfo method should simply return a string with the students name, numGrade, and letterGrade. If the student is named Marsha and her number grade is 92, the method should return "Student: Marsha, Number Grade: 92, Letter Grade: A". NOTE: You MUST use the get methods of each Instance variable for the studentsinfo method, NOT the Instance variables. Create a constructor for the Student class that takes in two parameter, A string for the name of the student and an int for the numGrade of the student. After you assign these parameters to your instance variable, invoke (use) the setLetterGrade method to set the leder grade. In the main method create 3 students, Place them in a Student array then in a for loop, print out every students info.

Write a function that takes a stack, finds and removes maximum element in it. The rest of the elements should stay unchanged after the function is done. If there is more than one identical maximum, remove all maximums. Assumptions you can use: • All elements are positive in a stack • If the stack is empty, return 0 Method signature: public static int stackMax (Stack<Integer> stack) Sample Input/Output: Single max element: Input Stack: 1 -> 2 -> 3-> 7-> 4 Function output: 7 Content of the stack: 1 -> 2 -> 3 -> 4 Multiple max elements: Input Stack: 1 -> 7 -> 2 -> 7 -> 3 -> 7-> 4 Function output: 7 Content of the stack: 1 -> 2 -> 3-> 4 Empty stack: Input Stack: Function output: 0 Content of the stack:
