Question 3 (60%) Figure below depicts a tapered elastic bar subjected to an applied tensile load P at one end and attached to a fixed support at the other end. The cross-sectional area varies linearly from A0 at the fixed support at x = 0 to Ao/2 at x = L. Calculate the displacement of the end of the bar (a) by modeling the bar using three bar elements of equal length having cross-sectional area equal to the area at the midpoint along the element length, (b) using four bar elements of equal length and similarly evaluating the area at the midpoint of each, and (c) compare displacements and stresses against the exact values defined as: $\delta = 1.386 \frac{PL}{A_0E}$ for the displacement of the end, and $\sigma(x) = \frac{P}{A_0(1-\frac{x}{2L})}$ for the stress distribution in the bar. A(x) = A_0(1 - \frac{x}{2L}) (a) (b) (c) Figure Q3 - (a) Tapered axial bar, (b) one-element model, (c) two-element model

Scrabble.java This class represents the Scrabble game in which there are seven randomly selected tiles, and scoring is performed for each possible word (this will be the tougher class to implement). The class must have the following private variables: • Tile (Tile[]) The class must have the following public methods: • public Scrabble() [constructor] • Initialize the Tile array and 'pickup' for random values • public Scrabble(Tile []) [constructor] • Initialize the tile array with the given argument • public String getLetters() • Return a string that is all of the tile characters (for example, "ABFEODL") • public ArrayList<String> getWords() • Create a String array with sn elements. Each element in this list should represent a word that can be created using the current tiles. • The algorithm for this method should reference the provided file CollinsScrabbleWords2019.txt ** do NOT put this file somewhere on your local machine and hardcode the local directory. This will likely cause your tests to fail on GradeScope. Also, do not put it within a folder in the relative path. • public int[] getScores() • Create an int array with n elements. Each element in this list should represent each individual score for each word that can be created using the current tiles. This should be returned in ascending order. • public Boolean equals(Scrabble) • Compare the given Scrabble object from the argument with the 'this' object to see if they are equal.
