SolidWork

what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a

Spur Gear : Machine Design

Spur Gear : Machine Design            In Introduction :                                      Slipping  of a belt or rope is the transmission of motion or power between two shafts. The effect of slipping is to reduce the velocity ratio of system . The motion and power transmitted by gears is equivalent to transmitted by functional wheel or disc . Advantages of Gear Drive :.          Transmits exact velocity ratio Transmit large power Used for small centre distance if shafts High Efficiency Reliability Service Compact Layout Disadvantages of Gear Drive :.    Require special tools and equipment Require lubricant and proper operation Vibration and noise during operation Classification of Gears :                    1. According to position of axes of shifts :.                                            Parallel - Spur Gear , Single Helical Gear , Double Helical , Rack and Pinion  Intersecting or Non - Parallel - Bevel Gear Non - Intersecting and Non - Parallel - Worm and Wormed Gear , Spira

Project is a task designed to accomplish singular goal . Such as developing software, product .  In project involves some batch work .  Project Management -  Project Planning Project Scheduling  Project Control  CPM - Critical Path Method PERT - Program Evaluation and Review Techniques CPM and PERT are used to project Scheduling. CPM and PERT are network models CPM was developed by ' Du Pont ' in 1950. PERT was developed by 'U S Navy ' in 1950. In beginning CPM was used to design chemical plant .  In beginning PERT was used to Polaris Submarine Launched Missile Project. CPM : Deterministic Approach Onetime Estimated  Activity
