The mass of the sign shown is 28.5 kg. Find the weight supported by (a) the left support and (b) the right support. How do I set this problem up properly? Here is my set up even though I know its wrong. m = 28.5kg, mg = 279.3N Fl + Fr = mg Fl = mg - Fr t = torque, r = radius tl + tr = mg Fl*rl + Fr*rr = mg (mg - Fr)*rl + Fr*rr = mg mg*rl - Fr*rl + Fr*rr = mg then I plug in the radius of the right and left posts using 1.2m for the left post and .3m for the right post, and 279.3 for mg and solve. How do I properly set this problem up?
