6.Calculation formula of power of rotary motion		Symbol description and unit
（1） torque	T=F*r　　　[kgf･m] T=	F：The power to work[kgf]
（1） torque	T=F*r　　　[kgf･m] T=	r： Radius [m]
(2-1)power	P_kW=Tωπ/(102*180)　　　[kW] P_kW=	T： torque　[kgf･m]
(2-1)power	P_kW=Tωπ/(102*180)　　　[kW] P_kW=	ω： Angular velocity [degree / s]
(2-2) power	P_kW=2πNT/(10260)　　[kW] P_kW=	N： Rotation speed[rpm]
(2-2) power	P_kW=2πNT/(10260)　　[kW] P_kW=	T： torque[kgf･m]
(3) Conversion of power unit	1kgf･m/s=9.8J/s=9.8W　　　 1W=0.102kgf･m/s=1J/s 1kW=102kgf･m/s≒1.36S 1PS=75kgf･m=0.736kW
