Firstly we need to take a metal rim smaller than the size of the wooden cart's wheel then we heat the metal rim, by which the size of the metal rim increases and then we need to keep it on the wooden cart's wheel and then cool it down by which it contracts a and then we see it tightly fixed to the wooden cart's wheel.
Hope this information clears your doubts about the topic.
Keep asking!!
