Explanation Given: Two chains suspended load of 500-lb at an angle of 45 ° . Definition used: When the system is in equilibrium state, the sum of all forces will be zero. Calculation: Use the given information to draw the figure in online graphic calculator as follows, From Figure 1, T 1 and T 2 are the tensional force in the chain and F is the downward force due to the load. Let the tensional force on the two chains be T 1 and T 2 . Let the downward force acting on the system due to suspended load be F . The vector form of T 1 = 〈 | T 1 | cos 45 ° , | T 1 | sin 45 ° 〉 , T 2 = 〈 − | T 2 | cos 45 ° , | T 2 | sin 45 ° 〉 and F = 〈 0 , − 500 〉 . Use definition of equilibrium state to add all the forces as, T 1 + T 2 + F = 0 T 1 + T 2 = − F 〈 | T 1 | cos 45 ° , | T 1 | sin 45 ° 〉 + 〈 − | T 2 | cos 45 ° , | T 2 | sin 45 ° 〉 = − 〈 0 , − 500 〉 〈 |

Lab 07: Java Graphics (Bonus lab) In this lab, we'll be practicing what we learned about GUIs, and Mouse events. You will need to implement the following: ➤ A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). о The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: о An input button to register your mouse to the drawing panel. ○ о о A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. The x position of the points cannot go further than the You can implement this GUI in any way you choose. I suggest using the BorderLayout for a panel containing the buttons, and a GridLayout to hold the drawing panel and button panels.…

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a) Give an example of when an application might want to receive such ICMP messages. (b) Find out what an application has to do, on the operating system of your choice, to receive such messages. (c) Why might it not be a good idea to send such messages directly back to the originating port P on A?
