Flexible Connectors in Mechanical Engineering Lesson IV Quiz

The speed of the rope is less than ______ m/s (600 fpm)

The angle of contact for the bigger pulley is ______ than the angle of contact for the smaller pulley

The surface speeds of the smaller pulley are the ______ as the bigger pulley

The belt speed is the ______ as the pulley's surface speeds

The speed ratio, $SR$, is calculated using the equation $SR = \frac{D_2}{D_1}$, where $D_1$ is the diameter of the smaller pulley and $D_2$ is the diameter of the bigger pulley

The belt length, $L$, is calculated using the equation $L = \frac{(D_1 + D_2)}{2} + 2C + \frac{(D_2 - D_1)^2}{4C}$, where $D_1$ is the diameter of the smaller pulley, $D_2$ is the diameter of the bigger pulley, and $C$ is the distance between the centers of the pulleys

The open belt connection is used for connecting parallel ______
