Where gear 1 is start from the bottom right gear and ends with gear 7 which is located at the top middle.
The shaft length are 20cm between gear 1 and gear 2,15cm between gear 2 and gear 3 and 15cm between gear 5 and gear 6. The material of the shaft and gear are made up of acetal which density is 1410kg/m3.
May i know how to calculate the input torque required in order turn all the gear?
no load are at the end of the gear, only mass moment of inertia of the gear and the shaft need to be consider. TQ for helping.
Torque= mass moment of inertia*angular acceleration
