Find the tension in each rope "torque"
1. A uniform plank of length 2m and mass 30kg is supported by three ropes. Find the tension in each rope when 700N person is 0.5m from the left end.
2. diagram

| /40 degrees ↓ (rotating clockwise)
←-----person-----------------/---
So i began with isolating the X and Y variables
ie: X on left, fcos40
y going up, fsin40
how would i go about breaking down the mass of the person + plank to figure out the tension in each rope?
