I wanna know how does this dynamic load helps in designing a robot?

Torque = alpha * I

isnt it I=mr^2Therefore, T=mr^2 * alpha

huh? in my torque formula i already have the angular acceleration (alpha)note: T=mr^2 * alpha

so basically you use the mr^2 * alpha equation for each point mass individually, then at the end you sum them all up . . .

Does that mean my total dynamic load is the sum of all the torque above?

If I reduced the point of mass for each component of the robot into a single point of mass and then I use the formula T=m*r^2 * angular acceleration, is it correct?
