A rod of length 70 cm and mass 2.6 kg is suspended by two strings which are 41 cm long, one at each end of the rod. The string on side B is cut. Find the magnitude of the initial acceleration of end B.

The string on side B is retied and now has only half the length of the string on side A. Find the magnitude of the initial acceleration of the end B when the string is cut.

Step 1

The bar has only one other force acting on it when string B is cut, and that would be gravity. The gravity always acts at the center of mass, or at a distance 35cm.

Write the expression for torque and equate with the torque due to force of gravity.

Step 2

Write the expression for linear acceleration, and solve for magnitude of the initial acceleration of end B.
