Concept explainers

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 2 You are holding a thin and weightless bar on your head (see figure 2.1). On the extremity A, the bar is attached to an elastic spring with unstressed length of 1 m and spring constant, k = 50 N/m; on the other extremity D, the bar is against a wall. On point C, a force F is applied, forming a 45-degree angle with the bar. Assign the length AE according to the height of your body. (a) What is the magnitude of the force F for the bar to rest horizontally? (b) If the force F was removed, what support would you need in D in place of the wall, in order to keep the bar at rest horizontally? Justify your suggestion(s).
