It works in conjunction with an axle and allows objects to roll, making it far easier to move heavy loads over a surface. The invention of the wheel is considered one of the most important developments in human history, revolutionizing travel, trade, and engineering. Early wheels were solid wooden disks, but over time, they evolved into more advanced designs, such as sp
