Engineering Mechanics - Dynamics Chapter 22 Problem 22-3 When a block of mass m 1 is suspended from a spring, the spring is stretched a distance δ . Determine the natural frequency and the period of vibration for a block of mass m 2 attached to the same spring. Given: m 1 3kg = m 2 0.2 kg = 60 mm = g 9.81 m s 2 = Solution: k m 1 g = k 490.50 N m = ω n k m 2 = n 49.52 rad s = f n 2 π = f 7.88 Hz = r 1 f = r 0.127 s = *Problem 22-4 A block of mass M is suspended from a spring having a stiffness k . If the block is given an upward velocity v when it is distance d above its equilibrium position, determine the equation
