Below are eight crates of different mass. (Figure 1) The crates are attached to massless ropes…
The net force on each of the crates is 0 since they are all travelling at the same constant velocity (it doesn't have to be equal, just constant). The tension in the pulling rope is thus perfectly matched by the frictional force in the horizontal direction, that is F = μkmg The tension in the ropeRead more
The net force on each of the crates is 0 since they are all travelling at the same constant velocity (it doesn’t have to be equal, just constant). The tension in the pulling rope is thus perfectly matched by the frictional force in the horizontal direction, that is F = μkmg
The tension in the rope is proportional to the mass that the rope is pulling because the coefficient of kinetic friction is the same and g = 9.81 m / s is constant. When we divide the rope tension by the corresponding letter, we get: A=D>E=H>B=F=G>C

Answer: C = F > B > E = A > D
Explanation:
The moment of inertia I is given by
I = mr2
Where: m is the mass and r is the distance of the center of mass from the axis rotation.
See lessSince the mass is the same for all cases, the differences in the moment of inertia in the different axes will depend on the distance r from the axis of rotation.
The moment of inertia at C and F are the largest because those are the axes that are farthest from the center of mass. Next to C and F is B. Then followed by E and A. The axis where the moment of inertia is the least is at D because the distance from the axis of rotation exceeds the radius of the balls.
