In a V-Belt Drive, it is said that when a New Belt is installed, the Tension Ratio shouldn't exceed 5:1. But isn't this ratio beyond control and is defined by T1/T2 = μ*α*cosecβ where T1/T2=Tension Ratio, μ=Coefficient of Friction, α=Angle of Wrap, β=Groove Angle of V-Belt. All of these variable...
Newton's Second Law (F=ma) is applicable only if you're working in the Inertial Frame of Reference (Earth or any other frame moving at a constant velocity wrt Earth). You don't even need D'Alembert Principle when working in this Frame.
However, when you're working in an Accelerating Non...
