Noramally 9.5 inches unless you have a special load on the joist.
To determine the appropriate size of a rolled steel joist (RSJ) for a 19-foot span with purlins on a roof pitched at 45 degrees, factors such as the load requirements, spacing of support beams, and material properties must be considered. Generally, a structural engineer would evaluate these factors and perform detailed calculations to ensure safety and compliance with building regulations. However, for preliminary sizing, an RSJ around 203mm x 102mm x 23kg/m could be considered, but consult a structural engineer for precise specifications tailored to your project.
That really depends upon the load you need to carry and the material that the beam is made of.
Adult octopus weigh around 33 lbs, with an arm span of up to 14 ft.
To determine the appropriate size of an I-beam for a 2000 lb center load over spans of 12 feet and 14 feet, you need to consider factors such as the beam's material, allowable deflection, and local building codes. Generally, for a 12-foot span, a W8x10 or W8x15 beam might suffice, while for a 14-foot span, a W8x15 or W8x18 could be more appropriate. It's essential to consult with a structural engineer to ensure compliance with safety standards and to account for additional factors like live load, dead load, and beam support conditions.
Span of control refers to the reach of management. A supervisor who has 14 employees has a span of control that encompasses those 14 employees.
