So here we can say that the torque is going to be equal to the forest times the length from the center of Mass and the length is going to be equal to our sign of theta. So. And if we choose counterclockwise to be positive, we can say that torques of one is going to be equal to force of one length sub one, and this would be equal to negative eight times five. So this would be negative 40 noon meters and then torques of two. But vehicle to out F sub to Elsa, too, and this would be equal to 12 times to sign of 30 degrees. This would simply simply be equal to positive 12 new colors. So when we find the sum of torques, this is simply going to be talks of one plus talks up to, and this will be negative 40 plus 12. And this is equally negative 28 Newton meters. So this would be your final answer, however, because it's negative and we chose counterclockwise to be positive. This would be this would produce clockwise rotation. Yeah, that is the end of the solution. Thank you for watching
