DataBase Concepts DataBase – a collection of information related to specific entity (e.g. organization‚ bank‚ college‚ library etc.) DBMS – (Database management system) – a application through which we can control the database i.e. we can store data into database‚ update the data and delete also we can retrieve the data from database. For doing these operation DBMS support a language called Structured Query language (SQL). SQL accomplishes many powerful tasks with a mere seven statements: SELECT

PROBLEM STATEMENT: The design is to engineer a drive system to operate two extrusion rolls in opposite directions to compress the caramel. The drive system consists of a flexible drive system that operates a spur gear drive‚ which in turn operates the extrusion rolls at equal and opposite speeds. The power source to this design is a five horse power normal torque AC electric motor‚ operating at 1160 rpm. The system must be designed to run 24 hours per day‚ 3 days per week. There will be 4 shafts
