Question on page two of the training manual of the Envelope principle. In the text it states that at any measured cross section the cylinder may be smaller than LMC. In the picture below it, it states that at any cross section the cylinder must not be less than LMC. I am thinking the picture is right unless I am missing something....
Yes, the image should read "may not be smaller than LMC size."
Tell me and I forget. Teach me and I remember. Involve me and I learn.
