You have to know that the slenderness ratio only takes into account the shape of the column. So because of that, the slenderness ratio is the same for steel, aluminium, wood, etc. The formula KL/r where K is the equivalent length factor, L the length of the column and r the radius of gyration which is sqrt(I/A), should always stay under 200. If not, you must redesign...
C25 concrete is a concrete having compressive strength of 25MPa when tested at the 28th day after casting. The specimen can be cube(150x150x150) or cylindrical(125mm by 250mm high). The cube strength has 0.8 times that of cylindrical specimen due to shape factor.
to choose a side o a shape
A wooded frame is made into a shape, for example a stair case, and then the concrete is poured into the frame. After the concrete has set, the wood/shuttering is removed, leaving a solid concrete shape. Steel bars are added into the concrete as it sets to give the shape more strength. Vague description but that the general idea of it, hope it helped.
The image is a similar shape to that of the original.
Using elastic section analysis it is proved to be 1.5
The distance of object and the distance of image.
The scale factor a shape and its image is the constant of proportionality (ratio) between the lengths of their corresponding sides.
They are 4 different images plotted on the Cartesian plane and they are:- Translation moves each point of a shape in the same distance and direction Reflection a mirror image of a shape Enlargement changes size of a shape by a given scale factor Rotation turns a shape at a given angle and at a fixed point
The image of a sphere shape is a circle, no matter what direction you look at it from.
1 shape cannot have a scale factor. A scale factor is something (a factor) that relates one shape to another.
shape of a image of cosipentagon or cosilaipentagon
thank you When an image or shape finds a reflection of itself to where it is an exact copy of that image or shape.
None of these transformations affect the size nor shape of the image.
None. The vertices, the scale factor as well as the centre of dilation can each be defined independently of the other two. Each different combination will result in a different image.
