Unformatted text preview: vectors with their tails at the point where the force is applied, and their arrows in the direction of the force. The length of the force vectors should represent to relative magnitudes of the forces (accuracy counts). d) Often in pulley problems we assume that the tension in the string is uniform throughout the length of the string. This is not the case in this problem. Explain why the tension in the string pulling up on m 1 is not equal in magnitude to the tension pulling up on m 2 . r v t P r L I L 2 2 1 I KE rot F r t L Object on Net L J Ang dt I dt L d...
