If the springs are attached asymmetrically with respect to the center of gravity of the weight in a very specific way, then yes.

Explanation:

If the weight #W# is to stay in equilibrium, the net force and the net torque on it must both vanish.

If the elongation #x# is the same in both the springs (spring constants #k_1# and #k_2#, respectively), then they will exert upward forces of #k_1 x# and #k_2x#, respectively. If the center of gravity of the weight is at distances of #d_1# and #d_2# from the points where the two springs are attached to it. we have

(Force balance) #(k_1+k_2)x = W#
(Torque balance) #k_1x times d_1 = k_2 x times d_2#

So, we must have

#d_1/d_2 = k_2/k_1#

for this to happen.
