FAQs about 8 45 Pound Plates
When you load 8 45-pound plates on each side of a standard Olympic barbell, you calculate the total weight by considering both sides along with the bar itself. Each side would have 8 plates, weighing 45 pounds per plate. Therefore, for one side it would be (8 \times 45 = 360) pounds. Since the load is on both sides, multiply by 2 to get (360 \times 2 = 720) pounds. Adding the weight of a typical Olympic barbell, which is 45 pounds, brings the total weight to (720 + 45 = 765) pounds. Thus, lifting 8 45-pound plates on each side totals 765 pounds.
45-pound plates tend to be more expensive due to several factors. Firstly, the cost of raw materials such as iron and steel, which are essential for producing durable and high-quality weight plates, significantly contributes to the price. Manufacturing processes involve casting, machining, and finishing, which require specialized equipment and skilled labor. Additionally, larger plates undergo stringent quality control checks to ensure safety and performance. Brand reputation also adds to the cost; reputable brands that offer better materials, warranties, and customer service usually command higher prices. Finally, logistical factors, such as shipping heavy items, further increase the overall cost of 45-pound plates.
The number of 45-pound plates that can fit on a standard Olympic barbell varies but generally, a bar can hold up to approximately 8-10 plates on each side. This is due to the barbell sleeve length, which is typically around 16.5 inches per side. Factors like the inclusion of a collar or the specific design of the plates (e.g., thickness) also influence the total number that can fit. For competition use, where collars and exact spacing are considered, fewer plates might fit. Practically, the maximum number often seen in gyms without overcrowding or compromising safety is about 8 plates per side.
While 45 pounds is the heaviest standard weight plate commonly found in most gyms, it is not the heaviest available. Heavier plates, such as 50-pound plates, 100-pound plates, and specialty plates used in certain strength sports and training facilities, also exist. These heavier plates are less common and typically not seen in many commercial gyms due to their specific use and the already substantial challenge posed by 45-pound plates. Specialty gyms, powerlifting, and weightlifting facilities may stock these heavier plates to meet the requirements of advanced and elite athletes.
