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.

Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.4 inches. -D -1.0000 Ø How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? The depth of the mill should be inches.
