Link BD consists of a single bar 30 mm wide and 12 mm thick. Knowing that each pin has a10 mm diameter, determine the maximum value of the average normal stress in the link BD if θ = 15 degrees.

Link will be apear in 30 seconds.

Well done! you have successfully gained access to Decrypted Link.

Question:

Create a class(in JAVA) for FileHandling with following members

1. Final and Static field named as “bookPath”, which holds the address for the file, i.e; “Databook.txt”
2. Final and Static field named as “authorPath”, which holds the address for the file, i.e; “Dataauthor.txt”
3. Static method to write data in file. It takes two arguments: data and file path. Data is inserted at the end of the file while previous data remains. Data is single line to write in the file.
4. Static method to read data from file. It takes file path and returns whole file data.

Create Main class containing main method and show the working of FileHandling class without creating the object.
