    All vibrating bodies have following DOF: a) 1 b)2 )3 d)4
    Please answer

      The correct answer is (b) 2. All vibrating bodies have two degrees of freedom (DOF) - one for displacement and one for velocity.

    How do we know that w2= root(3k/m) and w1=root(k/m) can you exam sir?

      In a two degrees of freedom (2-DOF) system, the natural frequencies 𝜔1 and 𝜔2 are determined from the system's dynamic equations, which are typically derived using methods like Newton's laws or Lagrange's equations.

    @The Mechanical Engineer check your answer for the second ratio of amplitude
    Isn't it the answer supposed to be -1 because k=k1=k1 and m1=m2 BUT you are having -2.79
    PLEASE RESPOND IT URGENT 🙏
