How much force must you exert to keep the pole motionless

Reference no: EM13544902

You're carrying a 4.0-m-long, 23kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35cm from its tip. How much force must you exert to keep the pole motionless in a horizontal position?
