CVCV Joint - Higher Pair Constraints

A cam is a rotating machine element which gives reciprocating or oscillating motion to another element known as follower. The cam and follower have a point or line contact constituting a higher pair. The contact between them is maintained by an external force which is generally provided by a spring or sometimes by the…

Section modulus is the ratio of moment of inertia about neutral axis upon the farthest point of section from neutral axis. A beam that has a larger section modulus than another will be stronger and capable of supporting greater loads, The section modulus is denoted by…

                                          Objective:

                                          Metal corrosion is currently explained by the formation of local electrochemical electrode pairs on the metal surface. The electrode pair is called an anode-cathode pair. Positive metal ions are dissolved from the anode to the solution, and produce negative electrons in the metal lattice, which migrate in the metal to…

                                            FREE FALLING BODY IN NEGATVIE Y DIRECTION

                                            Objective:

                                            Here the initial simulation is performed with the given values of  mass- 1 Kg Interia- 1 `(kg)/m^2` The result obtained at the end of simulation time period of 2 sec was distance of 19620 m in negative y direction. Simillarly, when the mass and intertia properties of the same body are changed the result obtained were…
