i'm still not sure how to approach this. Should I be using torque to solve for the person's mass? Isnt the force in question gravity? so torque=d*Fgrav?

Ok so can we equate the torque on one scale as the product of its radius and normal force acting on it?

Does the normal force of one spring scale equal Fgrav-normal force of the other spring?

Are the three forces Fn from each scale and Fgrav from the person onto the plank?

Oh sorry by radius I was referring to the distance from center of mass to each spring scale

Homework Statement Explain how you could measure both your mass and the position of your body’s centre of mass if all you had as experimental equipment was two spring balances (calibrated, of course), and a light, rigid plank, set up as shown in the figure. Figure: #1...
