एक कॉटर जॉइंट (cotter joint) का उपयोग दो सह-अक्षीय (co-axial) छड़ों को जोड़ने के लिए किया जाता है, जो ______ तन्य (tensile) या संपीडक (compressive) भार के अधीन होती हैं।

The dynamic load-carrying capacity of a radial bearing is defined as the constant radial load that the bearing can withstand for a rating life of how many revolutions?

If P = equivalent dynamic load, Fr = radial load, Fa = axial or thrust load, V = race-rotation factor, and X and Y are radial and thrust factors respectively, then the correct expression for equivalent dynamic load on a bearing is:
