Essentials of MRI Safety- corrections & clarifications

The following lists a number of corrections to the current published version.

Figure 2.21: The force at each end is T/l (torque divided by length). The equation stated in the caption is the total twisting forces on the object.

Example 2.7: The rotational force here is the sum of twisting forces on the ends of the object.

Example 2.8: Similarly 2057 N is the combined twisting forces.

Chapter 2 revision question 1: Option A. 1.4985 T

Chapter 7 p 164. The inverse probability weight adjusted risk of hearing loss is 1.04.

Examples 9.1, 9.2, 9.6, 10.6, 11.15: These calculations are for the net twisting forces on the object.

Chapter 11 p265: T/m not “T/s”.

Equation 11.3: similarly shows the sum of twisting forces.

Answers to revision questions: Chapter 2 question 5: the correct answer is C.
