Use the java. net. ServerSocket class to open a port and listen for new connections (see chapter 3 of the textbook for more information). Use the java. net. ServerSocket. accept() method to accept a new client connection. You can read from and write to the data streams in java. net. ServerSocket. getOutputStream() and java. net. ServerSocket. getInputStream() just as if they were files or standard input/output.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
