Chain strength
WebAssuming both the chain and wire rope are being used for lifting, and the cross-sectional area of the wire rope and chain are the same, in general the wire rope will have the larger yield strength, unless both are made out of a material with greater shear strength than tensile strength. WebJan 19, 2024 · So, the chain tension exerted by a 52-tooth chainring at 260 watts of power output and 126 RPM cadence is (176 N)/(4.45 N/lbf) = 40 lbf. And since 52 = 2 x 26, the …
