A cylinder is a figure in space that has two parallel bases. The bases are congruent non-polygons. It also has a curved surface. It has no vertex. If the line segment joining the center of the two bases is parallel to the sides and perpendicular to the bases, then the cylinder is called a right cylinder. Q1: What are the common types of tanks used for storing liquids in bulk? A1: Liquids are usually stored in bulk in vertical cylindrical steel tanks. Fixed and floating-roof tanks are commonly used. Q2: How does a floating-roof tank differ from a fixed-roof tank, and what are the advantages of using a floating-roof tank? A2: In a floating-roof tank, a movable piston floats on the surface of the liquid and is sealed to the tank walls. It is used to eliminate evaporation losses and, for flammable liquids, to avoid the need for inert gas blanketing, preventing the formation of an explosive mixture above the liquid. Q3: What types of tanks are used for storing relatively small quantiti...

A cone is a three-dimensional figure that has a closed curve for a base. This type of base is called a non-polygon. The surface of a cone comes to a point, called the vertex. An ice cream cone is an example of a cone. In a right circular cone, the line segment that joins the vertex with the center of the base is perpendicular to the base. Q1: What is a cone in three-dimensional space? A1: In three-dimensional space, a cone is the surface formed by an infinite collection of straight lines. These lines pass through one point of a fixed closed curve inscribed in a plane, known as the directrix of the cone, and through a fixed given point above the plane, referred to as the vertex of the cone. The lines drawn are called generators of the cone. Q2: What is the significance of the directrix and vertex in a cone? A2: The directrix of a cone is a fixed closed curve in a plane through which the cone's generators pass. The vertex is a fixed point above the plane through which the...

A sphere is the closed surface in three-dimensional space consisting of all those points that are a fixed distance r from a given origin point O is called a sphere. The length r is called the radius of the sphere, and the point O the center of the sphere. Q1: What does the term "sphere" refer to in both euclidean solid geometry and common usage? A1: In both euclidean solid geometry and common usage, a sphere denotes a solid of revolution obtained by revolving a semicircle of radius r about its diameter. Its total volume is V =4/3​ πr 3 . Q2: In analytic geometry, what does the term "sphere" refer to? A2: In analytic geometry, and more generally in modern mathematics, the word "sphere" denotes a spherical surface that bounds a solid sphere. It is the locus of all points P in three-dimensional space whose distance from a fixed point O (called the center) is equal to a given number. Q3: What is a tangent plane in the context of a sphere? A3: A plane tha...

Q1: What is the need of units of measurement? A1:  Units of measurement are essential for quantifying and comparing various quantities. They provide a standardized way to express the magnitude of physical properties, enabling communication and understanding among individuals in different contexts. Units help in establishing a common language for describing measurements, ensuring accuracy, consistency, and clarity in scientific, industrial, and everyday applications. Q2: Why to read this content? A2: Reading this content is important because it highlights the significance of units of measurement in practical scenarios. The example of splitting barley grain illustrates the challenges of distribution without specific measurement units. Understanding the common needs for measurement, the historical development of base units, and the relevance of unit conversion factors equips individuals, especially engineers, with the knowledge needed to navigate and solve real-world problem...
