3 Water is supported by a curved gate described by equation y=-xº. The gate is 5 supported with a string passing through the pulley as shown in the figure below. The water is filled up to a height of h=5 m and the string is connected to the gate at H = 7 m. Calculate the tension developed in the string. Assume acceleration due to gravity as 10 m/s² and width of the gate as 20 m. Р 3 H water a) 1200 kN b) 2381 kN c) 3621 kN d) 4361 kN

EXPERT ANSWER

pure formaldehyde gas (CH2O) is burned completely in air, using 50% excess air. a. What should be the Orsat analysis of the combustion gas? b. What should be the Orsat analysis of the combustion gas if instead of excess air, only enough were used to burn all the hydrogen to water, 25% of the carbon to CO2 and the remaining 75% to CO, the combustion being conducted that no oxygen gas whatever is left remaining in the combustion products

You are asked to implement the “cat” Linux command that concatenate and print files using JAVA programming language.In fact, you are asked to implement one option of this command namely the following:Command syntax: cp source file1 file2 filen > destination file,Example: cat source1.txt source2.txt source3.txt > destination.txt You should pass both, the source and destination file names as arguments to the executable.Develop a program in JAVA and call it “cat”, once executed it merges the file content of many source files to a destination file lactated in the same directory.For instance, the command:cat file1 file2 > file3.will sequentially print the contents of file1 and file2 to the file file3 the program should allow any number of source files. You are asked to provide the source code of your JAVA program.

Question 3: (6 marks) Write a shell script “cat.sh” that implements the Linux command “cat”. Where the content of a file is to be played on the screen. The “cat” command takes one argument from the command line: the argument is a file name. First it checks if there is one argument supplied on the command line, if not it shows an appropriate error message and it exits. Then it checks if the file exists, if not it shows an appropriate error message and it exits. If the file exists, then it reads it line by line. While reading the file content it displays them on them screen.

The pin P has a mass of 0.2 kg. It is constrained to move along the frictionless curved slot as shown. As the arm OA rotates, the radial distance between pin P and pivot O is constrained to follow the function r = (0.6cos2 m. The arm OA rotates with a constant angular speed θ =-3 rad/s. The whole thing is on the vertical plane (gravity cannot be neglected). At the moment when θ三0, determine: The normal force exerted on the pin by the wall. (Hint: at θ = 0 this force will be horizontal and along the er component. The normal force exerted on the pin by the arm OA. (Hint: at θ = 0 this force will be vertical and along the eθ component. The net normal force (magnitude) exerted on the pin. (Easy once you solved (a) and (b)) a. b. c. r (0.6 cos 20) m More hints on problem 5: Draw your FBD and IRD when θ 0, such that the reaction forces (from the wall and the arm) are horizontal and vertical, respectively. The only “body” in your FBD should be the pin. Dio not draw the arm or the track!!! Work this problem in polar coordinates!!! It will be nearly impossible to solve otherwise. The most tedious part of this problem is to derive an expression for ř and i (you need to take the derivative of r, which requires careful application of chain rule and product rule.) γ, γ and γ will be functions of θ, θ and θ, which have known values in this problem and you can therefore just plug in. You should end up with actual values for r,f and i. Use Newton’s 2″d Law using polar accelerations. (You should have one equation for the êr direction and another for the êa direction, The answer to part c is 5.75 N

You have been tasked to create a program that helps the customer service agents at your construction firm track the accounts that they handle. The two basic types of accounts are business accounts and personal accounts. Personal accounts track first name, last name, address, amount due, invoice date, and due date. Business accounts track the name of the business, address, amount due, invoice date, and due date. Create a base class named Account that contains the common properties of both types of accounts. Make sure to use the proper types for each of those properties (e.g., names are strings, dates should use the DateTime type, and money should use the Decimal type). Create two classes, one for personal accounts and one for business accounts. Inherit the information from the base Account class. In your application, create an instance of each type of the accounts that you defined. Set the properties you defined above to the following values for the personal account: FirstName – Your first name LastName – Your last name InvoiceDate – The current date DueDate – A month from the current date Set the following values for the business account: AmountDue – Any decimal value you would like BusinessName – Any string value you would like BusinessAddress – Any string value you would like Output the following to the console: Name (first and last for personal accounts, and business name for business accounts) Amount Due Due Date An example of the output would be: Name:John Smith AmountDue:$900 Due:12/1/2016 Name:AAA AmountDue:$9000 Due:1/15/2017
