CREATE TABLE table_2403 ("Length/Weight of Missile" TEXT, "Diameter of torsion spring" TEXT, "Height of torsion spring" TEXT, "Machine length" TEXT, "Machine width" TEXT)

When the torsion spring diameter is 38.4cm what would be the length or weight of the missile
SELECT "Length/Weight of Missile" FROM table_2403 WHERE "Diameter of torsion spring" = '38.4cm'
SELECT "Length/Weight of Missile" FROM "table_2403" WHERE "Diameter of torsion spring" = '38.4cm'
