TENSÃO MAX = TORQUE RAIO / ( PI RAIO ^4 / 2)
Tmax = T c /( PI C ^4 / 2 )
T c /( PI C ^4 / 2 ) = Tmax
T c = T max ( PI C ^4 / 2 )
T = (T max ( PI C ^4 / 2 ) ) / c
T = ( 60 X 10 ^6 Pa ( 3,14 ( 2,5 X 10 ^-2 m )^4 / 2 ) )/ 2,5 X 10 ^-2 m
T = ( 60 X 10 ^6 Pa ( 6,13 X 10 ^-7 m^4 )) / ( 2,5 X 10 ^-2 m )
T = ( 36,796 Pa m^4 )) / ( 2,5 X 10 ^-2 m )
T = ( 1.471,84 Pa m^4 / m)
T = (1.472 N/ m² m^4 ) / m
T = ( 1.472 Nm)
P = T W
T W = P
W = P / T
W = 85 KW / 1.472 Nm
W = 85000 W / 1.472 N m
W = 57,7 rad/s
57,7 rad/s = 9,19 Hz
