Free undamped vibrations

Whenever an object/system displaces in either side of its equilibrium position with the help of an external/internal means, then the object/system moves regularly or randomly on both sides of its equilibrium position. This motion is called vibration. Generally, there are three types of vibration: longitudinal vibration, transverse vibration, and torsional vibration.

Question

The uniform beam is supported at its ends by two springs
A and B, each having the same stiffness k. When nothing is
supported on the beam, it has a period of vertical vibration
of 0.83 s. If a 50-kg mass is placed at its center, the period
of vertical vibration is 1.52 s. Compute the stiffness of each
spring and the mass of the beam.

Let’s use an overly simplified model to investigate the difference in side impact safety between a convertible and a regular car.

Derive the spring rate k for the convertible. (k = F/δ, where δ is the deflection due to F.) Derive the free-body diagram for the regular car. Derive the spring rate for the regular car, by assuming that the horizontal beam does not buckle. Note: Need to take into account the compression of the horizontal beam.
