Question 9. How the water flow from a hydrant in a city water system measured ? Engineering drawing is a graphical language of an engineer to convey one’s ideas most effectively, easily, conveniently and with high speed. 5. The projections of a line are given. There are standard symbols for types of lines, types of letters, types of materials, types of sections, types of joints used in industry as well as daily life. 50. should be located below the metacentre. What is the ratio of damping coefficient to critical damping coefficient called ? . A1 (841 X 594), (i) annual loss of revenue on account of power head lost due to friction. The standard size of sheets according to I.S.I. Sectional view: The object is cut by a vertical plane to see the internal invisible details in the front view. Engineering Drawing Interview Questions & Answers. All the sectional views are meant to see and understand the internal invisible details of the object. Aligned system of dimensioning is more common. Mention clearly the units and sub units below the scale constructed. 22. Discuss Some Key Features About The Projection Of Points? 11. If distance is in front of VP, top view is below xy and vice versa. Siphon spillway is spillway designed to discharge water in a closed conduit under negative pressure. of the student, Type of symbol for the method of projection. If the line is inclined to H.P., it will have a H.T., (horizontal trace). What is the difference between steady and unsteady flow ? 47. It is a ratio of size taken on drawing sheet to the actual size of the object. Question 23. (iv) spherical pair—three degrees of freedom. ? On what factor the size of cam depends ? Name various functional elements of an instrumental system ? It is proportional to the square root of the distance from the leading edge. What Is A ? These are normally put from left to right whether written on a horizontal/vertical/inclined dimension. Define Engineering Drawing. It will give the overall size as well as sizes different parts of the object. Then flow = area of hydrant x. Turbulent flow is characterised by random and erratic movements of fluid particles resulting in formation of eddies. Question 39. What Is Meant By Conventions In Drawings? What do you understrand by inversions and how many inversions are possible in a kinematic chain having ‘n’ links ? What is the purpose of D-slide valve in steam engines ? 83. The line specified as thick is usually 3 times thicker and the line specified as medium is 2 times thicker than a thin line. Question 32. How does the head change in pipe flow with change in diameter, if capacity is constant. Ans: (i) Revolute pair—single degree of freedom. Pycnometer is used to measure specific gravity of the liquid. For example a scale in cm and mm is a plain scale, m and dm is another plain scale. What are the three functions served by a surge tank in a hydro plant ? Mark ten points on the left side of zero. Which Are The Types Of Projections Done In Engineering Drawing? 51. The ratio of change of momentum of a mass of fluid is equal to the vector sum of all external forces acting on it. For example a sheet of paper is a lamina. Why Is The Layout Of Sheet Is Necessary? What Are A Single And A Double Stroke Letters? Projection on a plane to which it is inclined will be less than the true length. If the line is inclined to HP, its top view on HP will be shorter than the true length. The principal planes of projection are three: P.—Vertical plane for a front view 90. P.—Profile plane for left or right side view of an object. It is used to determine velocity of flow in pipe. Home » ENGINEERING DRAWING Questions » 300+ TOP ENGINEERING DRAWING Interview Questions and Answers. What is the difference between lower pair and higher pair ? It will help in the right manufacturing as well as in repair and servicing of the object.
