2 parallel rods 8m apart are yield together by a steel bag 25mm passing through metal plate and nuts
at each other end. The nuts are screwed up to
the plate while the bar is at the
temperature of 150°C . Find the pull force
Converted
by the bar
the bar after
after it have pulled
at 40°C.
a. If the walls do not yield
b. If the total yielding at the two ends.​
