I've wished there was a way to view the current temperature on my HomeScreen. Especially in our cold winters. Up till now the only way was with a jailbroken iPhone. Now its possible without jailbreak.
Damaged or broken motor mounts are arguably the most serious cause of engine vibration. CarsDirect.com suggests that a driver shift between drive and neutral while the vehicle is sitting still. If the vibration lessens while in neutral, the motor mounts may have sustained damage.
Free vibration takes placewhen the system oscillates due to the action of internal forces only. Forced vibration is caused by the action ofexternal forces. If the frequency of excitation coincides with the natural frequency of the system, resonanceoccurs.
