That question cannot be answered without knowing the load on the beam.
To determine if an 8x8 PT (pressure-treated) beam can span 18 feet with a live load of 70 psf, you would typically need to refer to span tables or structural engineering guidelines. Generally, an 8x8 beam is not sufficient to span that distance under such a load without significant deflection or failure. It’s advisable to consult a structural engineer for an accurate assessment and proper design.
To find the area of a room, you multiply its length by its width. For a room that is 18 feet by 14 feet, the area would be 18 x 14 = 252 square feet. Therefore, the room is 252 square feet in size.
If you are 18 years old and weigh 104 lbs and stand 5'3" in height, your foot size will vary greatly depending on your bone structure and your sex. If your feet are size 3-4 in kids, you might have a very small frame which would be normal. The average foot size for a woman who is 5'3" in height is about size 5 to size 8 in adult women's shoes. How big your feet are is most likely normal for your size.
18-in = 1.5 feet18-in x 18-in = 1.5-ft x 1.5-ft = 2.25 square feet48 tiles of this size have total area of (2.25 x 48) = 108 square feet
180 square feet will fit a room 12 x 15.
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.

The maximum allowable span for a triple 2x10 beam according to building codes and regulations is typically around 15-18 feet, depending on the specific building code and load requirements in your area. It is important to consult with a structural engineer or local building department to ensure compliance with regulations.
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
This is one of those questions that no one will will tackle because there are other factors that weigh into this type construction: Angle of lift, How will the new beam be supported, Is the foundation sufficent, indoors vs outdoor ect. Your safety is important, and you would be better served to discuss your needs with a engineer that can look at the whole picture. I built a overhead crane once with a 40' span once and I can tell you from experience you will not find a beam straight enough as delivered. It will have to be proffessionaly straightened. Mine was a 24 x 100# I-beam and it had a 18" bow that had to be corrected.

For a 20ft span, a typical glulam beam size would be around 5-1/8" x 18-1/2" or 6-3/4" x 15-1/2". The actual size needed may vary depending on the specific load requirements and building codes in your area, so it's recommended to consult with a structural engineer or supplier to determine the appropriate size for your project.

A blaster beam makes the long metallic sound in movies. It is usually a metal beam that is 12 to 18 feet in length.
