What is Engineering Machanics ? |Deformable bodies.|Strength |Stiffness |Assumption in a som equation |
Q. What is Engineering Machanics ? Answer :- It is mechanics of rigid body. If the relative position of the particles doesn't change even in the presence of external forces. then it is rigid body. Study of external force & their effects. MOS It is mechanics of deformable bodies. Here deals with the study of internal resistive forces. Deformable bodies. Change in dimension/shape change. Resistance that has a tendency to oppose the change. The basic objects of strength of materials to drive the expression for stresses, strans, deformation that are developed due to the external force, these are used in designing a component. Strength :- Ability of a material to resist failure against external forces. The maximum stress that can be developed just before Failure is called strength. It is material property and is const for a given material. It is primary design parameter. Stiffness :- Ability of a material to resist deformation. material property. sec...
