What incline can a vehicle weighing system be off by?

The correct answer of 4.5 degrees indicates the acceptable range of incline that a vehicle weighing system can accommodate without significantly affecting the accuracy of the weight measurement. Weighing systems, particularly those used in commercial applications, are designed with tolerance limits that allow for some degree of variability in incline. If the incline exceeds this specified amount, it can lead to inaccurate readings due to the influence of gravitational forces on the measurement.

A steep incline can shift the weight distribution of the vehicle and alter the pressure on the load cells or weighing pads used in the system, resulting in errors in the recorded weight. Thus, maintaining the incline within 4.5 degrees helps ensure that the system operates correctly and the readings remain reliable.
