The drive-shafts are connected to the differential and wheel hubs through universal joints because the universal joints Compensate for variations in the relative positions of the differential and the wheels which result from bumpy road surfaces or other similar driving conditions.
A tachometer is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine.
The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common.
When indicated power (I.P.) and frictional power (F.P.) are known, we can calculate
The main characteristics of a maintenance free (MF) battery is that Since it is sealed, the water in maintenance free battery is not lost through evaporation thus accordingly it is not necessary to top up the cells with water
If the engine coolant leaks into the engine oil, then engine oil
