WebDec 14, 2024 · This will be the distance out at a perpendicular angle, that is, 90 degrees, from the center. If the handle is not at a perpendicular angle, as some ratchet adapters allow, then envision an imaginary line extending from the bolt. The length will be the perpendicular distance from this imaginary line to where force is applied on the ratchet handle. WebOct 21, 2012 · For calculating minimum force to engage or disengage these parts we can use the following formula F = μ . pmax . A Where μ is the friction between hub and shaft, A is the area of contact between shaft and …
