Mass changes inertia and natural frequencies;damping dissipates energy. Added mass can move a mode toward or away from an excitation frequency,so monotonic improvement is not guaranteed.<\/p><p>The old geometry also contradicted its own mass result. It multiplied one cube dimension by 1.5 and rounded all dimensions upward,but continued using the smaller target mass for soil pressure. The displayed block could therefore contain much more concrete than the pressure calculation assumed. This worksheet instead requires L and W and solves H exactly from the target volume.<\/p><p>Universal claims for minimum concrete grade,depth as a multiple of machine width and reinforcement mass per cubic metre were removed. These are structural\/geotechnical design decisions,not consequences of machine mass alone. Defaults,pump\/compressor\/fan presets,silent density\/bearing fallbacks and prefix-tolerant <span class=\"fm-code\">parseFloat<\/span> input were also removed.<\/p><\/section>\n<section class=\"fm-section\"><h2>Dynamic-design scope and sources<\/h2><p><a href=\"https:\/\/www.concrete.org\/store\/productdetail.aspx?ItemID=351318&amp;Language=English&amp;Units=US_AND_METRIC\" target=\"_blank\" rel=\"noopener\">ACI PRC-351.3-18, Report on Foundations for Dynamic Equipment<\/a> is the current ACI Committee 351 report listed in the 2025 ACI Collection.
