- Homework Statement:
- A 6 spoke wheel with a radius of 2 meters has 4 - 1 Kg masses hanging from the point where the spoke meets the rim as shown. What would be the net torque acting on the wheel?

- Relevant Equations:
- Applying Rotational equlibrium, F1d1 + F2d2 = F3d3 + F4d4

F_{1}d_{1} + F_{2}d_{2} = F_{3}d_{3} + F_{4}d_{4}

m_{1} gR cos 60 + m_{2}gR cos 60 = m_{3}gR cos 60 + m_{4}gR sin 90

m1 = m2= m3= m4= m

R1=R2=R3=R4=R

\sigma\tau = sin 90 - cos 60 = 0.5 Nm.

Have I done this right?

m_{1} gR cos 60 + m_{2}gR cos 60 = m_{3}gR cos 60 + m_{4}gR sin 90

m1 = m2= m3= m4= m

\sigma\tau = sin 90 - cos 60 = 0.5 Nm.
