. (1) The American ideal of a lush green lawn is borrowed from England, where the cool, misty climate makes it easy to grow grass. (2) In America, however, lawns are an energy-intensive, wasteful, and nonproductive form of landscaping. (3) To begin with, achieving a picture-perfect lawn requires gallons of expensive fertilizer and hazardous pesticides that pollute groundwater and run off into lakes and rivers. (4) In addition, lawn owners often exterminate the insects, moles, and gophers that play a part in the balance of nature. (5) Equally destructive is the constant watering lawns require, often where water is a limited resource. (6) Finally, the lawn must be mowed on a regular basis to give it that green carpet effect, requiring endless output of human and mechanical energy. (7) After all the labor and expense, the final result is a flat carpet that lacks interesting features, wildlife, or edible produce.

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.

Knowing that the central portion of link bd has a uniform cross sectional area of 800 mm2 , determine the magnitude of the load p for which the normal stress in link bd is 50 mpa. (hint: link bd is a two-force member.) ans: p = 62.7 kn
