0 FizziksGuy Posted September 21, 2013 Share Posted September 21, 2013 To begin with, let's identify the forces on the beam. The force of gravity (the weight of the beam), is mg, or 225kg*9.8 m/s2=2205 Newtons downwards. The crane lifts the beam by applying a force of 2430N upwards. The net force, then, must be 2430N-2205N = 225N upwards The beam's acceleration can be found from Newton's 2nd Law, Fnet=ma, so a=Fnet/m=225N/225kg=1 m/s2 upwards.
