Solution:
QUESTION: 7

The friction radius for designing a clutch with uniform pressure theory is given as

Solution:
QUESTION: 8

For a multiplate clutch with number of driving flange = 3 and no. of driven flange = 2 no. of contact surface is.

Solution:

In a multi plate clutch, number of pairs of contact surfaces (n) is equal to n1 + n2 – 1. Due to the high number of pairs of contact surfaces, the torque transmitted is higher.
n is always a whole number.
