A reversible compression of 1 mol of an ideal gas in a piston/cylinder device results in a pressure increase from 1 bar to P2 an
d a temperature increase from 500 K to 1000 K. The path followed by the gas during compression is given by:
PV1.55 = constant
and the molar heat capacity of the gas is given by:
CP/R = 3.30 + 0.63x10-3 T (T in K)
Determine the final pressure and the heat transferred during the process.

Answer:
maximum isolator stiffness k =1764 kN-m
Explanation:
mean speed of rotation
=65.44 rad/sec
= 0.1*(65.44)^2
F_T =428.36 N
Transmission ratio
also
transmission ratio
SOLVING FOR Wn
Wn = 42 rad/sec
k = m*W^2_n
k = 1000*42^2 = 1764 kN-m
k =1764 kN-m
