A plate clutch consists of one pair of contacting surfaces and transm...
Given,Power,P = 20 kW, N = 750 rpm,
Μ = 0.2, Pa = 1 N/mm2,D = 2d
Torque required to engage clutch,
= 254647.91 N-mm
Force required to engage clutch
d = 102.62 mm

Given data:
Power transmitted = 20 kW
Speed = 750 rpm
Ratio of outer diameter to inner diameter = 2
Coefficient of friction = 0.2
Permissible intensity of pressure = 1 N/mm2
Formula Used:
Power transmitted by clutch = (π/30) * μ * P * (r2^2 - r1^2) * N
Where,
μ = Coefficient of friction
P = Permissible intensity of pressure
r1 = Inner radius of clutch
r2 = Outer radius of clutch
N = Speed in rpm
Calculation:
Given,
Power transmitted = 20 kW
Speed = 750 rpm
Ratio of outer diameter to inner diameter = 2
Let the inner diameter of clutch be 'd'.
So, outer diameter = 2d.
r1 = d/2
r2 = 2d/2 = d
μ = 0.2
P = 1 N/mm2
Substituting the given values in the above formula, we get
20 = (π/30) * 0.2 * 1 * (d^2 - (d/2)^2) * 750
Solving the above equation, we get
d = 102.62 mm
Therefore, the inner diameter of the clutch is 102.62 mm.

Solving the above equation, we get
d = 102.62 mm
Therefore, the inner diameter of the clutch is 102.62 mm.
