2PRACTICE PROBLEM
A uniform pine plank of length 2 m and a mass of 15 kg is held by a carpenter and his son. The carpenter applies a vertical force of magnitude 40 N at the left end. Find i) the magnitude and ii) the point of application of the force that the son should exert to maintain the board stable. Start by drawing a free-body diagram of the plank.
