Free response of SDOF
                    When there is a reduction in amplitude over every cycle of vibration, then the body is said to have
                  
                  
                  
                
                  
                    Longitudinal vibrations are said to occur when the particles of a body moves
                  
                  
                  
                
                  
                    When a body is subjected to transverse vibrations, the stress induced in a body will be
                  
                  
                  
                
                  
                    The natural frequency (in Hz) of free longitudinal vibrations is equal to
