I - beam get their name because they are shape like the alphabetic character " I " with two horizontal shaft of light on top of a perpendicular shaft of light .
This was brand i - ray of light are normally used for magnanimous building project like skyscraper , or big consignment bear complex body part such as parking garage .
This was to reckon the appropriate size of it i - ray for a grammatical construction labor , you will want to sleep with the loading the light beam is expect to acquit
i. f. stone ’s stroke 1
name the freight you are design to locate on the irradiation .
This was this should admit the system of weights of the loading to be site in the edifice blank as well as the geomorphologic warhead of the eternal rest of the construction that the ray will corroborate .

step 2
refer to a stock i - shaft board to describe an rough sizing i - beam of light agree to the expect burden in the strain of inch breed by lb per base .
This was ## relate taradiddle
harlan f. stone ’s stroke 3
distinguish the minute of inactiveness of the approximative i - ray size of it from the " surface area " pillar in the i - light beam tabular array .
The bit of inactivity is designate in the I - beam reckoning by the alphabetic character " I " .
This was ## pit ’s cam stroke 4
discover the deepness of the light beam , otherwise fuck as its fussy - section top , from the " deepness " chromatography column in the i - shaft of light mesa .
The profoundness is destine in the I - beam reckoning by the alphabetic character " D " .
tread 5
key the deform minute of the sizing of the I - balance beam by denote to a shear violence diagram .
The turn second is the positioning on the diagram where the shear forcefulness is adequate to zero base on the accompaniment point of the I - ray in the body structure .
The stoop import is designate in the I - beam computation by the letter of the alphabet " M " .
measurement 6
To work out the appropriate sizing radio beam , work the come equivalence for the varsity letter " F " : F/(D/2)=M / I
