Geometric modelling:
Geometric modelling is an integral part of any Computer-Aided-Design (CAD) system. Integration of geometric modelling; computer graphics along with design principles develops CAD tools. Therefore, in this unit, a brief treatment of representation of curves is presented. Curve representation in parametric form would increase the graphical representation of curves apart from ease of computation. Synthetic forms of curves such like Hermite cubic B-Splines, Bezier, B-Splines and Nurbs have been extensively used to represent several practical situations being modelled in CAD systems. A detailed treatment of these curves is presented. The features of Wire-frame models and its applications are also discussed.

GAS METAL ARC WELDING-PRINCIPLE OF OPERATION Gas Metal Arc Welding (GMAW) is one of the arc welding processes in which an electric arc is formed and maintained between a continuo
Friction: When a body moves or tends to move over the other body, a force opposing the motion develops at the contact surfaces. This force that opposes the movement or the ten
STEP S FOR SOLVING PROBLEM FOR FINDING POWER: 1. Use formula stress (s) = force (Maximum Tension)/Area Where; Area = b.t that is, Tmax = σ.b.t 2. Unit mass (m) = r.b.t.
