Q:A rectangular plate of sides a and b is supended from a ceiling by two parallel strings of length L each(Fig). The Separation between the strings is d. The plate is displaced slightly in its plane keeping the strings tight. Show that it will execute SHM. Find the time period

Basic SHM equations:
1.F=-kx
2.T=(2*pi)/(omega)
Let the plate be displaced a slightly for a displacement x and the angle of strings with vertical be theta.
2Tsin(theta)=-ma
Using Approx.
sin(theta)=x/L
-2Tx/L=-ma
I don't know how to eliminate T from the equation. Plz help!
