ERGONOMICS EXERCISE |
||
A: The measurement from the ground to the lower back. |
||
Exercise: Select twelve people at random from your
class. Collect the measurements A, B and C and work out the average for

Draw a basic diagram of a person sat at a picnic table.
Identify the most important measurements that need to be calculated in

||
The table below is a sample. It shows measurements A, B and C arranged in table form with the average for each worked out. The average measurements are then used to help design and make an chair that has been based on sound ergonomic factors. |
||
The diagram below shows a picnicker ready to eat his
lunch. Add three important ergonomic measurements that must be calculated
if the table is to be ergonomically designed. These measurements can be
called A, B and C. |
