1. Hi all. Can anyone please help me find the torque required for rotating a shaft which has two masses 1000 Kg each at 120 Degree angles. Please refer to the attachment for clarity.
ok then. since both the masses are at 120 deg angle. what is the total mass i should i consider. should i add 1000+1000 = 2000 Kg or should i calculate the resultant mass? can u help me in finding the resultant mass?
OK, (though I'm still wondering why the drawing shows them as clearly of different lengths).
How about writing an expression for the torque about the axis of rotation as a function of angular position? You can call zero angle at any position you like.
Take one bar at a time. What's the torque gravity applies to one of the bars as a function of its angular position?
