Design documents state that a total of six M10 x 1.5, class 5.8 bolt and nut pairs fasten a 15 mm thick steel cap to a 15 mm thick steel flange. Safety requirements dictate that this fastening system must possess a safety factor of 1.5. Use the preload determined in Part A when calculating the bolted joints safety in dynamic loading in Part B. (Note: One may find km using the method outlined in class, or one may use Eqn. 15.19 on p. 929). a) If the steel cap experiences a static external load of 30 kN, is this design safe? b) If the steel cap experiences an external load that varies from 10-20 kN and the bolted joint must be 99% reliable, is this design safe?

A purely competitive nut and bolt manufacturer faces a market price of $7.00, an average total cost of $7.50, an average variable cost of $6.00, and a marginal cost of $6.75. Should this firm expand output, contract output, or shut down in the short-run? Use a graph to illustrate your answer, making sure to indicate these price and cost values

Design a class named GeoPoint to represent a point with x- and y-coordinates. The class contains: The data fields x and y that represent the coordinates with gette and setter methods. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. The method equals(GeoPoint p) that returns true if two GeoPoint objects have the same x- and y-coordinates. Write a test program that creates an array of GeoPoint objects. The size of...

Design a class named MyPoint to represent a point with x- and y-coordinates. The class should contain: Two data fields x and y that represent the coordinates. A no-arg constructor that creates a point at (0, 0). A constructor that creates a point with specified coordinates. Get methods for data fields x and y respectively. A method named distance that returns the distance from this point to another point with specified x- and y-coordinates. Use the formula: root (x2-x1)2 +...

Design a class named Robot. The Robot class has three private data fields: position x, position y, and the direction (east, south, west, and north). Assume that positive x points to the east and positive y points to the south, and initially x = 0, y = 0, direction = "east". Create a no-arg constructor and another constructor which sets the three data fields. Create the accessors and mutators for the three data fields. Create a method named forward that...
