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.
The space truss is supported by a ball-and-socket joint at D and short links at C and E. Determine the force and stress in each member and state if the members are buckle or

Find out bulk modulus: A steel bar of 25 mm diameter was tested on a gauge length of 250 cm in tension and in torsion. A tensile load of 50 kN generated an extension of 0.13 m
Structural Steels Low alloy steels are utilized for structural causes. That type of steels is needed to possess high yield stress, excellent ductility and high fatigue resist
(a) Why do we change the engine oil at periodic intervals? (b) What are the recommended instructions to change engine oil? (c) How will you measure the engine oil level?
define prandtl''s stress function
(a) Draw neatly and accurately the Merchant force circle diagram. Mention clearly the forces involved, the constructional steps and the assumptions made [do not derive the forces]
Base Circle: this is the smallest circle tangent to the cam profile. Trace Point: this is theoretical point on the follower whose motion explained the movement of the foll
