4.3 ANALISYS OF DURABILITY

2) Load weight analysis

Weight Object added (Kg) Length of Smaller

Cylinder Pipe (cm)
0kg 12.5cm

6kg 12.4cm

8.50kg 12.4cm
11kg 12.3cm

16kg 12.3cm
25kg 12.3cm

29kg 2.3cm

Table 4.1: Result of durability

Weight of Toolbox part = 12kg

Minimum Load = 29kg + 12kg

Minimum Load = 41kg Maximum Load = 120kg

As shown in Table (1), The time trial result of Task A (changing engine oil)
st
activities by using 3 attempts. At the 1 attempts, Hydraulic Toolbox Chair
took 12 minutes to did the Task A meanwhile the normal toolbox chair took
nd
17 minutes to settled the Task A. At the 2 attempts Normal Toolbox
finished 3minutes earlier than before and the Hydraulic Toolbox Chair took
15 minutes to finish Task A. At the last attempts, Hydraulic Toolbox Chair
finished 5 minutes earlier than Normal toolbox which is the Hydraulic
Toolbox Chair took 10 minutes and 15 minutes for the Normal Toolbox. At
the Average, to finished the Task A (changing engine oil) Hydraulic Toolbox
Chair took 12.33 minutes to finish the Task A and the Normal Toolbox took
15.33 minutes to finished the Task A

In the Table (2) the time trial result for Task B (Time taken to retrieve the
st
appliance from the toolbox) by using 3 attempts. At the 1 attempts Hydraulic
Toolbox Chair recorded 3 seconds and Normal Toolbox took 8 seconds to
nd
finish the Task B. At the 2 attempts, Normal toolbox recorded 5 seconds
meanwhile Hydraulic Toolbox Chair recorded 4seconds to finish the Task B.
At the last attempts, Hydraulic Toolbox Chair recorded 3 seconds earlier than
