Subtopic: Human engineering and safety considerations in design of tractor and agricultural implements
Question Statement:
According to the OECD Standard Code 4 for official testing of tractor Roll-Over Protective Structures (ROPS), the minimum energy requirement ($E$) to be absorbed during the lateral side loading test for a tractor of reference mass $M = 3000\text{ kg}$ is given by:
$E = 1.4 \times M\text{ Joules}$
The required lateral energy absorption capacity of the ROPS in $\text{kJ}$ is ________ (round off to 1 decimal place).
Answer Key:
4.2
Step-by-Step Solution & Explanation
1. Energy formula from OECD Code 4:
$E = 1.4 \times M = 1.4 \times 3000 = 4200\text{ J}$
2. Convert to $\text{kJ}$:
$E = \frac{4200\text{ J}}{1000} = 4.2\text{ kJ}$
