A spring has a stiffness of 600 N/m, if a 4 kg block is attached to the spring, pushed 500 mm above its equilibrium position, and released from rest; determine the angular frequency. Assume the positive displacement is measured downward
A helical spring with a mass of 6 kg has a mass of 10 kg attached to its free end. The mass is now pulled down to 40 mm from the equilibrium position and then released. Determine (a) the frequency of the oscilliation if the spring's stiffness is 532 N.m, (b) the angular velocity of the mass, (c) the instantaneous linear velocity and (d) the kinetic energy of the 10-kg mass when it is 30 mm from the equilibrium position.
If both springs are usntretched when the mass is in the central position shown, determine the static deflection of the mass. What is the period of oscillatory motion about the position of static equilibrium? The mass m = 3.4, the spring constant k = 295 N/m, and the angle theta = 31 degrees
