The vegetable cart moved with the help of a cow. The owner does not have to do much work in this case as pulling the cart is taken care by the cow he just has to weigh the vegetables and collect cash. Also the cart can take weight as much as 1000 kgs. 
Iron frame wooden planks for base. Can carry a weight of almost 200kgs.
Around 7 racks are there on a single frame n each compartment can hold 9-10 magazines or paper. Each panel is 20-30 inches above ground level and 60 inches in height. Easily approachable by the customer so the shopkeeper just sits n collects cash.
This cycle is usually used to carry waste from houses.. Can take a load of up to 20-25 kgs each side. Mostly used for papers n cardboard waste. An average person or even a small child can carry it.
There are 4 racks and 5 compartments each in a row. The average height of a person being 5ft 4” that is around 64-65 inches it is idly made for an average heighted person to even reach till the top compartments.
The machine table is made with a height, length and width suitable for a person to work on the table and as the legs are 16 inches and moving the panel down takes up the legs 4 more inches there is sufficient space between the table and legs. The area next to the machine is good enough to keep the fabric there while working. 
Ergonomic was one of the assignment which helped me understand the human body relation to his work surroundings. Why certain things are designed in a certain way was best understood by the help of this exercise. Even the smallest of businesses have innovated way to make life simpler or to make the most of minimum resources.
These machines are designed in a way that it is conducive for human use and less hard work has to be performed.This type of research also helps to understand to what extent the human body has to be stretched while performing any activity in the course of his work.
