The ratio of the maximum shear angel to the minimum shear angle during machining is _________, A sphere of diameter 12 cm, is dropped in a right c ircular cylindrical vessel, partly filled with water. d
As with two dimensional space the standard \(\left( {x,y,z} \right)\) coordinate system is called the Cartesian coordinate system. d q d What distinguishes orthogonal coordinates is that, though the basis vectors vary, they are always orthogonal with respect to each other. Mathematics CBSE class 10 2015, Let P and Q be the points of trisection of the line segment joining the points A(2, -2) and B(-7, 4) such that P is nearer to A. , Find the diamet er o, A cylindrical workpiece is turned at a feed of 0.1 mm/rev with a perfectly sharp tool. described below. , 2

× These basis vectors are by definition the tangent vectors of the curves obtained by varying one coordinate, keeping the others fixed: where r is some point and qi is the coordinate for which the basis vector is extracted. ∞ ) 2 )
) A point P(R1, θ1, φ1) in spherical coordinates is located at the intersection of the following three surfaces: The base vectors meet the following relations: In vector calculus and electromagnetics work we often need to perform line, surface, and volume integrals. r ⋅ The feed during cylindrical turning is 0.1 mm/rev. , {\displaystyle {\begin{aligned}&(\lambda ,\mu ,\nu )\\&\nu ^{2} In the context of small oscillations, which one of the following does NOT apply to the normal coordinates?

Answers Cylindrical coordinate system is orthogonal : Cartesian coordinate system is length based, since dx, dy, dz are all lengths. h ) i , [ (B) orthogonal to ⃗ alone. d 2 ) For example, the three-dimensional Cartesian coordinates (x, y, z) is an orthogonal coordinate system, since its coordinate surfaces x = constant, y = constant, and z = constant are planes that meet at right angles to one another, i.e., are perpendicular. , ) ϕ ) ∞ q , However, in other curvilinear coordinate systems, such as cylindrical and spherical coordinate systems, some differential changes are not length based, such as dθ, dφ. × = ∞ ) ( {\displaystyle \scriptstyle {\mathcal {P}}} ) ∞ × {\displaystyle \scriptstyle {\mathcal {S}}} 2 , We made eduladder by keeping the ideology of building a supermarket of all the educational material available under one roof. ) × μ i In mathematics, orthogonal coordinates are defined as a set of d coordinates q = (q1, q2, ..., qd) in which the coordinate surfaces all meet at right angles (note: superscripts are indices, not exponents). h e ν q Suppose we define a new orthogonal coordinate system, such as spherical coordinates defined by ν 2 i ] , h ^ v e ) d μ 2 In the more general setting of curvilinear coordinates, a point in space is specified by the coordinates, and at every such point there is bound a set of basis vectors, which generally are not constant: this is the essence of curvilinear coordinates in general and is a very important concept. ( "I think I know enough of hate". 2 u e < × 0 2 Mathematics CBSE class 10 2015, If the distances of P(x, y) from A(5, 1) and B(-1, 5) are equal, then prove that 3x = 2y. × h 0 h ℓ 0 h , ( e However, in other curvilinear coordinate systems, such as cylindrical and spherical coordinate systems, some differential changes are not length based, such as … ν 3 ( × The rake angle was 10° and the axial feed was 100 mm/min. j ( 0 [ {\displaystyle (u,v,z)\in [0,\infty )\times [0,2\pi )\times (-\infty ,\infty )}, ( ) 3 d 3 μ d Pass any exams with this 100 proven techniques Just Rs - 130/- Only for a year. 2 From the above discussion, we can see the differential length changes dl1, dl2, dl3 are: where h1, h2, h3 may be functions of u1, u2, and u3. r = ) 0 ^ , Extra considerations may be necessary for other vector operations. j In the Cylindrical Coordinate System, any point of the space is represented using three coordinates that are ρ, φ and z. q b < | Thus, we need a conversion factor to convert (mapping) a non-length based differential change (dθ, dφ, etc.) Mathematics CBSE class 10 2016, CE 2043 DESIGN OF PLATE AND SHELL STRUCTURES. ∈ = λ h b {\displaystyle dS_{k}=h_{i}h_{j}\,dq^{i}\,dq^{j}}, d = Note that the summation symbols Σ (capital Sigma) and the summation range, indicating summation over all basis vectors (i = 1, 2, ..., d), are often omitted. {\displaystyle J=h_{1}h_{2}h_{3}} 0 q However, in other curvilinear coordinate systems, such as cylindrical and spherical coordinate systems, some differential changes are not length based, such as dθ, dφ. , [ q d ∞ π × q Many equations can be reduced to Laplace's equation or the Helmholtz equation. , 2 (Below address is used for communiation purposes only we are a group of ) i ∞ You might be intrested on below oppertunities Eduladder career: We have a robust ATS developed on the top of famous open source ATS called open cats the APIs which we have built on the top of the same will deliver the best and suitable job to the visitor who is browsing in our platform.
