The 26-kg uniform rectangular plate is supported by an ideal pivot at O and a spring which must be compressed prior to being slipped into place at point A. If the modulus of the spring is k = 2.4 kN/m, what must be its undeformed length L? 0.31 m 0.13 m 0.49 m 0.19 m 0.14 m The 26-kg uniform rectangular plate is supported by an ideal pivot at O and a spring which must be compressed prior to being slipped into place at point A.
