The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 4.2 s. If R = 1.3 m and m = 4.7 kg, calculate the angular momentum about that axis 41 28 067 46 13 041 63 71 Rotation axi 2R dy Number Units the tolerance is +/-2% GO TUTORIAL LINK TO TEXT LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM Question Attempts: Unlimited SAVE FOR LATER SUBMIT ANSWER I'm Cortana. Ask me anything 11:50 PM 4/27/2016Explanation / Answer
moment of inertia of hoop about the given axis, I_hoop = 0.5*m*R^2 + m*R^2
= 1.5*m*R^2
moment of Inertia of square about the given axis, I_square = 2*m*R^2/3 + m*R^2
= (5/3)*m*R^2
Total moment of inertia = 1.5*m*R^2 + (5/3)*m*R^2
= 3.167*m*R^2
angular momentum = I*w
= I*(2*pi/T)
= 3.167*m*R^2*(2*pi/T)
= 3.167*4.7*1.3^2*(2*pi/4.2)
= 37.6 kg.m^2/s
