Homework Statement
The 19.6 cm diameter disk rotates on an axle through its center. F1=22.8 N, F2=32.5 N, F3=32.5 N, F4=22.8 N, and d=4.60 cm. What is the net torque about the axle?
Homework Equations
Torque = F r sin (angle)
F = m g
The Attempt at a Solution
I found all the torques acting on the center, disregarded T1 because its sort of passing through the center and isn't really shown on the diagram.
T1 = 0
T2= (32.5)(0.196) = 6.37 Nm
T3= -(32.5)(sin 45)(0.046)= -1.057 Nm (counterclockwise)
T4= (22.8)(0.046)= -1.0488 (counterclockwise)
Tnet = 4.26 Nm
This isn't the right answer, can someone please help and explain where I am going wrong..
