Answer to Question #298835 in Mechanical Engineering for Luke

Question

A lamella coupling according to the figure below has friction surfaces between the diameters 135 and 105 mm. The coupling works with the surface pressure 36 N / cm2 and the friction number between the friction surfaces is 0.3. The lamella package is compressed by springs with the spring constant 610 N / cm per spring.

1. What force do the springs compress lamella packages with?
2. How much are the springs compressed?
3. Determine the transferable torque if we assume that the frictional force attacks the average radius
