Write a program to take input for n book records from user and write those book records in a file named: ”record”, whose price is less than INR 500 . Program should also perform random access in the file, after taking input for a particular record number to read and it should also perform random record overwriting after taking input of new record and the record number to overwrite. After overwriting record, display all records on the screen [Attributes of book: Book_id, Book_price, Book_name, Book_author_name]

An element in biaxial stress is subjected to stresses σx = −16 MPa and σy =42 MPa, as shown in the figure. Using Mohr's circle, determine:
(a) the stresses acting on an element oriented at a slope of 1 on 2.5 (see Fig Q1)
(b) the maximum shear stresses and associated normal stresses. Show all results on sketches of properly oriented elements.
