### If you slice a rectangular pyramid perpendicular to the base but NOT through the apex what will be the shape of the cross section?

It will be one of: a triangle if where the cross section cuts the base is through two adjacent sides; an irregular quadrilateral if where the cross section cuts the base is through two opposite sides but not parallel to a side of the base; or a trapezium if where the is the cross section cuts the base is parallel to a side of the base.

### What is the definition of a uniform cross-section?

A Uniform Cross Section is the cross section of the solid, parallel to base, such that the resulting figure has the same shape and size as that of the base of the figure. More about Uniform Cross Section Solids like pyramids and cones have slant heights and hence do not have uniform cross section. Examples of Uniform Cross Section The uniform cross section of the given prism is a square. The uniform cross section of…

### What is the difference between forging and extrusion process?

Forging is a process in which the material is given shape by giving localized compressive forces in the form of hard blows of hammer whereas extrusion is a process in which the material is given shape by pushing through a die of fixed cross section such as to produce objects of desired cross section.

### Where is a Cross section of bicycle pump?

a cross section applies to anything...it is a way of looking at something inside. imagine cutting through a pump (for example) and then looking perpindicular at it, like holding it out in your hands like binoculars, the shape that you see (a circle probably in this case) is called the cross sestion.

### How does a fin of a fish function?

Because the shape of a fin is flat and thin, it has a very narrow cross-section in one direction and a much larger cross-section in a perpendicular direction, consequently, a fish can use the fin to guide its motion through water; effectively, the fin makes it easier for a fish to move in a forward direction and less likely to slip sideways. There are also movable fins which can be used to actively push the…

### What is a column of air of unit cross sectional area?

A unit cross-section, as defined by the SI system of measurement, is 1 metre2. So a column of air is all the air in a vertical column whose cross sectional area is 1 m2. The exact shape of the cross section is not defined but it is normally circular or a square. A unit cross-section, as defined by the SI system of measurement, is 1 metre2. So a column of air is all the air…
