Question Bank of Analysis of Plane truss and Complex stresses  1. Relationship between Young's Modulus and Modulus of Rigidity. E= 2G (1 +  μ ) Where, E- Young's Modulus G- Modulus of rigidity μ - Poisson's ratio 2. Relationship between Bulk Modulus and Young's Modulus. E= 3K (1 - 2 μ ) Where, E - Young's Modulus K- Bulk Modulus μ - Poisson's ratio 3. What is principle of super position? The resultant deformation of the body is equal to the algebraic sum of the deformation of the individual section. Such principle is called as principle of super position 4. What is compound bar? A composite bar composed of two or more different materials joined together such that the system is elongated or compressed in a single unit. 5. What you mean by thermal stresses? If the body is allowed to expand or contract freely, with the rise or fall of temperature no stress is developed, but if free expansion is prevented the stress developed is called temperature stress or strain...

  Question Bank Mechanics of Solid (TORSION) 1. Define Torsion When a pair of forces of equal magnitude but opposite directions acting on body, it tends to twist the body.  It is known as twisting moment or torsion moment or simply as torque. Torque is equal to the product of the force applied and the distance between the point of application of the force and the axis of the shaft. 2. What are the assumptions made in Torsion equation The material of the shaft is homogeneous. Perfectly elastic and obeys Hooke's law. Twist is uniform along the length of the shaft The stress does not exceed the limit of proportionality The shaft circular in section remains circular after loading Strain and deformations are small. 3. Why hollow circular shafts are preferred when compared to solid circular shafts? The torque transmitted by the hollow shaft is greater than the solid shaft. For same material, length and given torque, the weight of the hollow shaft will be less  compared to solid...

SHEAR AND BENDING IN BEAMS 1. What is beam? Beam is a structural member which is supported along the length and subjected to external loads acting transversely (i.e) perpendicular to the center line of the beam. 2. What is mean by transverse loading on beam? If a load is acting on the beam which perpendicular to the central line of it then it is called transverse loading. 3. What is Cantilever beam? A beam one end free and the other end is free is called cantilever beam. 4. What is simply supported beam? A beam supported or resting free on the support at its both ends. 5. What is mean by over hanging beam? If one or both of the end portions are extended beyond the support then it is called over hanging beam. 6. What is mean by concentrated loads? A load which is acting at a point is called point load. 7. What is uniformly distributed load. If a load which is spread over a beam in such a manner that rate of loading is uniform through out the length then it is called as uniformly distrib...

  Question Bank of Geotechnical Engineering  (Slope Stability)  1. What is slide ? The failure of a mass of soil located beneath a slope is called a slide. 2. The causes for failure of slope. The action of gravitational forces, and Seepage forces within the soil. Failure due to undercutting of its foot. Failure due to disintegration n of the structure of the soil. 3. The types of slope. Infinite slope If a slope represents the boundary surface of a semi-infinite soil mass, and the soil properties for all identical depths below the surface are constant, it is called an infinite slope. Finite slope If a slope is of limited extent, it is called finite slope. 4. Basic types of failure of a finite slope. Slope failure Base failure 5. The types of slip surfaces or failure surfaces Planner failure surface Circular failure surface Non- circular failure surface 6. The method of analysis for stability of a finite slope Culmann's method of planner failure surface The Swedish circle ...

STRENGTH OF MATERIAL (DEFLECTION OF BEAMS) 1. What are the methods for finding out the slope and deflection at a section? The important methods used for finding out the slope and deflection at a section in a loaded beam are Double Integration Method Moment Area Method Macaulay's Method The first two methods are suitable for a single load, where as the last one is suitable for several loads. 2. Why moment area method is more useful, when compared with double integration? Moment Area Method is more useful, as compared with double integration method because many problems which do not have a simple mathematical solution can be simplified by the ending moment area method. 3. Theorem for Conjugate Beam Method? Theorem I: The slope at any section of of a loaded beam, relative to the original axis of the beam is equal to the shear in the conjugate beam at the corresponding section Theorem II:  The deflection at any given section of a loaded beam, relative to the original position is equal ...

  Question Bank of Paint 1. What is paint? Paint is a liquid surface coating which protect the surface from the weathering action of atmospheric agencies and provide a decorative finish. 2. What are the ingredients or the compositions of paint. Paint consists of : Base Vehicle Pigments  Solvents  Driers  Adulterants. 3. Write short note of ingredients of paint?  Base: It is the principal constituent of the paint, usually a metallic oxide. It makes the paint film opaque and possesses binding properties. Eg: White lead, Red lead, Zink white, Alumunium powder, Iron Oxide Vehicle: It is also known as binder. Vehicle is an oil to which holds the constituents of paint in suspension and helps to spread it over the surface to be painted.  It imparts durability, Toughness, water proof ness to the paint film, resistance to weathering, glossy finish to the painted surface and forms the body of the paint.  Eg: Linseed oil, Nut oil, poppy oil, Tung oil etc. Pigment...

  Question Bank of Design of Steel Structural 1. What are the various types of connections used for connecting the structural members? Riveted connections Bolted connections Pin connections Welded connections 2. Define nominal diameter of rivet. It is the diameter of the rivet shank.  3. Define gross diameter of rivet. It is the diameter of the rivet in the hole, measured after driving.  It is taken equal to the diameter of the rivet hole. Gross diameter = Nominal diameter + 1.5 mm, ϕ ≤   24 mm.  Gross diameter = Nominal diameter + 2.0 mm,  ϕ > 24 mm. 4. What is meant by gauge distance and edge distance? Gauge distance is the perpendicular distance between two adjacent gauge lines. This is also called as back pitch.  Edge distance is the distance of the edge of the member or the cover plates from the Centre of extreme rivet hole. Or it is the distance between the Centre of the outermost rivet and nearest edge of the member or cover ...
