Question

the belt drive ratio is also used to find the torque transmitted through a belt drive. the formula is proportional to the drive ratio. directly inversely acutely differentially

Explanation:

Torque in a belt drive is inversely proportional to the drive ratio. As the drive ratio increases (e.g., smaller - diameter pulley driving a larger - diameter pulley), the torque increases, but the relationship follows an inverse proportion. For example, if the drive ratio \(r=\frac{d_1}{d_2}\) (where \(d_1\) is the diameter of the driving pulley and \(d_2\) is the diameter of the driven pulley), and torque \(T\), we have \(T\propto\frac{1}{r}\) (assuming power transmission is constant, \(P = T\times\omega\), and \(\omega\propto\frac{1}{r}\)).

Answer:

Inversely
