Homework Equations
τ = I*α
τ = r*F
The Attempt at a Solution
EDIT2: Nevermind, manipulated the torque equations wrong, got it now
EDIT: Tried again and ended up with an actual answer, but still got it wrong :/
This is the FBD I used http://puu.sh/4PH7l.png
m = 1060 kg
Ft2 = 10900
I = 75.5 kg*m^2
r = 0.757 m1060a = Ft1 - 1060*9.81
τ = I*r*a
τ = r*F
F = 10900 - Ft1
I*r*a = r*F
I*a = F
75.5*a = 10900 - Ft1
1060a = Ft1 - 1060*9.81
Ft1 = 1060a + 1060*9.81
75.5a = 10900 - Ft1
75.5a = 10900 - (1060a + 1060*9.81)
75.5a = 10900 - 1060a - 1060*9.81
1060a + 75.5a = 10900 - 1060*9.81
a = (10900 - 1060*9.81) / (1060 + 75.5)
= 0.44157
