Mechanical failures account for about 12% of all road collisions. These failures can include issues like brake failures, tire blowouts, and engine problems, which can lead to accidents if not addressed promptly. Regular maintenance and checks on vehicles can help prevent these types of collisions.
If a machine was 100 percent efficient, the AMA would be equal to the IMA. This is because in an ideal scenario where the machine loses no energy to friction or other factors, the AMA (actual mechanical advantage) would be the same as the IMA (ideal mechanical advantage).
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
Theoretical mechanical advantage is the ratio of the input force to the output force without considering friction, while actual mechanical advantage includes frictional losses in the machine. If a machine is 100 percent efficient, there will be no frictional losses, so the theoretical and actual mechanical advantages will be the same, resulting in a 1:1 ratio of input force to output force.
Electric induction motors typically have an efficiency of over 95 percent. These motors are commonly used in various applications such as industrial machinery, appliances, and electric vehicles due to their high efficiency in converting electrical energy into mechanical energy.
To calculate the mechanical energy provided by the motor, you need to divide the input energy by the efficiency of the motor. In this case, with 70% efficiency, you would divide 1960 joules by 0.70 to find that the mechanical energy provided would be approximately 2800 joules.
100%. There are no accidents with motor vehicles. There are only failures to avoid collisions.

I am uncertain if that particular statistic is accurate, but the vast majority of collisions ARE caused by driver inattention or error.
