51. Let the forces that compress stoppers Aand Bbe FAand FB, respectively. Then equilibrium of torques about the axle requires FR = rAFA+ rBFB. If the stoppers are compressed by amounts |ΔyA| and |ΔyB| respectively, when the rod rotates a (presumably small) angle θ(in radians), then |||.ΔΔyrAABB==and |Furthermore, if their “spring constants” kare identical, then k= |F/Δy| leads to the
