Hello, I would like some help with the following question. I highly appreciate your help ! I got an answer that doesn't make sense so I know there must be a concept that I don't get. There is a complicated piece of machinery sitting on a plank of metal which is 2 m long. The metal and machinery have a combined mass of 430 kg. The center of mass is approximately 1.2 m from the left side of the plank. We need to attach 2 springs to the plank to lift it off the ground, but it needs to be level. One spring has a spring constant of 2200 N/m and is attached to the right edge of the plank. If the other spring has a spring constant of 1500 N/m, where should we put it to make sure everything is level? So what I did is that I wanted to balance torques and forces. Forces: mg= Fs1 + Fs2 mg= 2200Δx + 1500 Δx ( Since it is level, then I assumed that delta x is the same) mg = 3700 Δx 430*9.8= 3700 Δx Δx = 1.4 Then, I started balancing torques. I have set the left end to be my pivot. mg(1.2)= Fs2y ( Where y is the distance of the second spring from the left end) mg(1.2) = KΔx y 430*9.8*1.2 = 1500*1.4 y y = 2.4 , which is obviously impossible since the length of the plank is just 2 metres.
