Improvement of wheel and joint of luggage - Assignment Example

Wheeled luggage is one of the innovations created to ease travel. Over the last one hundred years, there has been an increase in the number of people travelling across the world. This is because of technological breakthrough in aviation, sailing, and motor vehicle engineering. Travelers include students, tourists, and business executives. Wheeled luggage makes traveling very convenient. It makes it easy for travelers to tow their luggage easily without straining their backs. Today, there are various versions of wheeled luggage, which include duffel bags, carry-on bags, backpacks, and totes.

A well-designed luggage may become useless if its wheels break down regardless of the durability of the luggage.

In this sense, the life of luggage depends on the durability of the wheels. There are three key conditions that luggage wheels need to meet in order to perform optimally. These are the ability to support the weight of the luggage, ability to handle torque and friction during motion, and the capacity to carry the full weigh of the luggage without collapsing. When the luggage is in motion, the entire weight of the luggage rests on the axles of the wheel. This means that the wheels require the capacity to support this weight without breaking.

The popular models of the luggage have two wheels located axially. The design of the axle must take into account the forces acting in the wheels. Poor
