Question

A plank of length L 2.000 m and mass M 4.00 kg is suspended horizontally by a thin cable at one end and to a pivot on a wall

Answer 1

Answer #1

In order to balance the plank by the cord, the Torque around the pivot should be 0.

T Tsino d Tcose

1)We take the x and y components of tension in the string along the x and they axis

2) Balance the torque around the pivot by balancing the torques due to weight of the plank and tension of the string.
