I have considered this problem for many years. Today I did a Google search on ‘calculating turning radius’ and came up with information that shows many are baffled by the concept. Do any ergoweb members have a formula for calculating turning radius? I am most interested in using the calculation for space planning in office situations, but over the years, I have had several situations where I could have used more precise method of determining space issues.
