Standardize the Unit of Torque as Joule per Radian (J/rad) Instead of Newton-Meter (N·m)
Masalahnya
Petition Summary:
We call upon the International System of Units (SI) and global scientific bodies to standardize Joule per Radian (J/rad) as the official unit for torque, replacing the ambiguous Newton-meter (N·m). This change will eliminate confusion between torque and work/energy, improving clarity in physics, engineering, and education.
Why This Matters:
1. Ambiguity in SI Units – Currently, both torque and work/energy are expressed in N·m, despite being fundamentally different quantities. Torque is a vector (rotational force), while work is a scalar (energy transfer). This leads to misinterpretations in academic and industrial contexts.
2. Clarity in Scientific Communication – Using Joule per Radian (J/rad) aligns torque directly with its definition: energy per unit angular displacement. This mirrors the linear counterpart (work = force × displacement), making equations more intuitive.
3. International Consistency – Many fields, such as mechanical engineering and physics, already use J/rad in practical calculations. Formal adoption would unify scientific literature and teaching materials.
Proposed Change:
Officially define torque in Joules per Radian (J/rad) within the SI system.
Encourage textbooks, research papers, and engineering standards to transition to the new unit.
