ABSTRACT
Wheelbarrow is a simple machine, which belong to the second-class lever. This is because the load or resistance is placed between the effort and the fulcrum. It is used in many areas of work to convey loads that are too heavy or bulky to be carried by hand. Wheelbarrow can be used as farm equipment, industrial equipment among others.
However, the efficiency of the wheelbarrow depends on the materials used for the construction. A wrong choice of these materials can reduce the efficiency and the life span of the machine.
Although no machine can operated with 100 percent efficiency because the friction of its parts always use up some of the energy that is being supplied to the machine. But friction can be decreased by oiling any sliding or rotating parts.
Moreover, depending on the type/size of machine to be constructed, the materials are reduced to smaller and more convenient sizes. The shapes and forms are changed by the following constructional operations, marking out, cutting, drilling, filling, recurring, taping broaching, folding/bending, welding, surface coating etc.
Most of these operations may be carried out by use of manual or mechanized processes depending on the size of the workshop.
In conclusion, a fixed amount of load was placed on the wheelbarrow to determine the efficiency and the effort required to lift the load. And according to the result gotten, the machine is highly efficient and required a very small effort to move objects many times their own size.
