Question

Introduction Many doors in public places are fitted with simple and inexpensive mechanisms that are designed to close the doors while reducing the slamming force to a minimum. Figure 1 Figure 1 depicts one such mechanism while Figure 2 provides a schematic description. The spring is mounted in order to push the door back to close once it is opened. The role of the hydraulic dashpot is to provide a viscous force that will prevent the door from slamming against the doorframe thus reducing the noise and physical damage.
