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...

Governor's : Theory of Machine

Governor's : Theory of Machine  Introduction : 1. A governor is a device which is also known as speed limiter or controller . 2. The function of governor is to regulate the mean speed of an engine , when variation in the load . 3. When load on an engine increases its speed decreases therefore increases the supply of working fluid . 4. When the load on an engine decreases it's speed increases therefore decreases the supply of working fluid . 5. Governor's automatically controls the supply of working fluid to the engine . Difference between governor and flywheel : 1. Flywheel can minimise fluctuation of speed within the cycle but governor can minimize fluctuation in mean speed of engine . 2. Flywheel can not minimize fluctuation due to load variation  but governor can minimize fluctuation of load variation . 3. Flywheel operation is continuous but governor operation is intermittent . 4. Flywheel is mounted on engine shaft to reduce torque fluctuation . Types of Governor : Gov...

QnA : Theory of Machine

QnA of Theory of Machine : 1. Inversion of a mechanism is - One link of kinematic chain is fixed . 2. For simple harmonic motion of a cam follower , a cosine curve represents - Acceleration Diagram . 3. Hartnett governer could be classified under the head of  spring controlled . Spring controlled - Hartness , Hartung , Pickering , Wilson - Hartness governer . 4. Normally cam moves with  constant velocity . 5. A simple mechanism has four links . 6. When the speed of governer increases then  height of governer decreases but radius of rotation increase . 7. The purpose of flywheel in an IC Engine is to reduce the vibration in the engine . 8. The pitch point on a cam exiest on - point on cam pitch curve at which pressure angle is maximum . 9. The stress in disc type flywheel as compared to rim type flywheel is greater . 10. The contact between cam and follower is to form a higher pair . 11. Governer is used in automobile to - control SN . 12. In order to Balanced the reciproc...

Cams : Theory Of Machines

Cams : A cam is rotating machine element which gives reciprocating or oscillating motion to another element know as follower . The cams are widely used for operating the inlet and exhaust values of internal combustion engines , automobile attachment of machineries ,paper cutting machines , spinning and weaving textile machineries ,feed mechanism of automatic lathes etc. Classification of Followers : 1. According to surface in contact : (a) Knife edge follower  (b) Roller Follower  (c) Flat Faced or Mushroom Follower (d) Spherical Faced Follower 2. According to the motion of follower : (a) Reciprocating or Translating follower  (b) Oscillating or rotating follower 3. According to path of motion of follower : (a) Radial follower  (b) Off - set follower Classification of cams : 1. Radial or disc cam  2. Cylinderical cam Terms used in radial cams : 1. Base curcle  2. Trace point  3. Pressure angle 4. Pitch point 5. Pitch circle 6. Pitch curve 7. Prime circ...

Gear Train : Theory of Machines

  Gear Train : Two or more gear are made to mesh with each other to transmit power from one shaft to another . Such a combination is called gear train or train of toothed wheels . The nature of the train used depends upon the velocity ratio required and the relative position of the axes of shafts . Types of Gear Train : Depending upon the arrangement of wheels - 1. Simple gear train 2. Compound gear train 3. Reverted gear train 4. Epicyclic gear train 1. Simple Gear Train : When there is only one gear on each shaft , it is known as simple gear train. The gears are represented by their pitch circles . The speed ratio or velocity ratio of gear train is the ratio of the speed of the driver to the speed of the driver or follower and ratio of speeds of any pair of gears in mesh is the inverse of their number of teeth . Train value is the reciprocal of speed ratio . The motion from one gear to another , may be transmitted by either of following two methods . 1. By providing the large siz...
