Pressure Gauge
how do you weigh a car using only a ruler and a pressure gauge?
the car is a jeep with obviously 4 tires. how do i find out how much it weighs? using only a ruler and a pressure gauge.
check the pressure of the 4 tyres. take an average of pressures of 4 tyres. then measure the contact surface( L*B) of the tyres with the ground by ruler. take the average of contact surface of 4 tyres .
Then it is simple:
Weight = Pressure in kg/cm^2 * Area in cm^2
