It has important theoretical value and practical engineering significance. 1 Introduction With features of light weight, low cost and simple construction, truss structure is playing an increasingly important role in the engineering and applied science, which is widely used in the fields of mechanical engineering, bridge designing, architectural structures and high voltage distribution network construction.
The material properties of square steel are as follows: E = 206GPa, μ=0.3 ρ=7850kg/m3 Where E is the elastic modulus, μ is the Poisson's ratio and ρ is the density.

The study was conducted on eighteen subjects, required to drill wood material using electric drill for 5 and 15 minutes.
There were two experiments taken for each subject using equipments to drill wood materials for two different duration periods. 2.3 Experiment Apparatus 2.3.1 Drilling machine The portable drilling machine (Bosch GBM 450 RE, approx. weight 1.5 kg, ø4 mm, 450 W) was used in this study.
