35 cm(1m/100cm) = 0.35 m
Applying rotational equilibrium:
mg(3.8/2) = F(3.8 - 0.35)
You're carrying a 3.8-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 35 cm from its tip.
How much force must you exert to keep the pole motionless in a horizontal position?
