The formula to calculate the Total Tension in Tight Side is:
\[ T_{t1} = T_{c} + (T_{t2} - T_{c}) \cdot e^{\mu \cdot \theta_{contact}} \]
Total tension in tight side is determined by measuring the force to deflect the belt a given distance per inch of pulley. Centrifugal tension of belt is the tension caused by centrifugal force. Total tension in slack side is determined by measuring the force to deflect the belt a given distance per inch of pulley. Coefficient of Friction for Belt is the ratio defining the force that resists the motion of the brake pad in relation to the brake disc or drum in contact with it. The angle of contact is the angle subtended by the belt on the pulley.
Let's assume the following values:
Using the formula:
\[ T_{t1} = 12.51 + (8 - 12.51) \cdot e^{0.2 \cdot 0.17} = 7.84402342365619 \]
