Web7 Mar 2024 · Keep in mind that this pulley has a total of four torques acting on it, one from each of the four belt/line segments: two from the bottom and two from the left. Other than that, be mindful of your own convention (you get to decide) of what direction is positive and what is negative. WebIf more than one torque acts on a rigid body about a fixed axis, then the sum of the torques equals the moment of inertia times the angular acceleration: ∑i τ i = I α. ∑ i τ i = I α. The term I α I α is a scalar quantity and can be positive or negative (counterclockwise or clockwise) depending upon the sign of the net torque. kylie christmas collection 2020Web28 Mar 2024 · However, if you have to work it out yourself, you'll need to know the mass of the object and the acceleration of the object in m/s 2.
