Correction for Scherrer et al., Characterizing sliding and rolling contacts between single particles

Key Points

This correction addresses dimensional inaccuracies in equations related to torque and force calculations.
Identified errors in Eq. (2) and Eq. (4) that affect dimensional correctness.
Provided correct formulations to ensure proper calculations of torque and force balance.
Reiterated the correct derivation based on geometric representations from Fig. 2.
Corrected Eq. (2) to align with dimensional requirements by adjusting torque calculations.
Clarified Eq. (4) to prevent miscalculations by repositioning a symbol.
Confirmed that these corrections do not affect the overall results or conclusions of the original manuscript.

Abstract

The authors note that Eqs. ( 2) and (4) appeared incorrectly."In the case of Eq. ( 2), the current version of the equation is not dimensionally correct, i.e., the torque M 0 must be divided by R p too to ensure correct dimensionality.In the case of Eq. ( 4), the symbol 1 should appear on the other side of the equality.The first error causes the units of part of Eq. ( 2) to be erroneous, but it does not affect any of the following results or conclusions of the manuscript.The second error would lead a reader to the wrong calculation of the values of 1 .However, repeating the derivation of the force and torque balance from Eq.(3) based on the geometry displayed in Fig. 2 would lead to the correct solution.We used the correct derivation in all the following parts of the manuscript that use the values of 1 for further calculations.This is just a typo in the equation and does not affect the reported data."On page 3, Eq. ( 2) should instead be written as:
