1 A student carries out an experiment to investigate the relationship between the

extensions of a spring, x, and weight of load, w.

Diagram 1.1 shows the arrangement of the apparatus for the experiment.

Seorang murid menjalankan satu eksperimen untuk mengkaji hubungan antara

pemanjangan suatu spring, x, dengan berat pemberat, w.

Rajah 1.1 menunjukkan susunan radas untuk eksperimen tersebut.

Diagram 1.1

Rajah 1.1

At the beginning of the experiment there is without load. The length of the spring

is, lo= 15.0 cm.

A load of weight, w = 30 N is used and the reading is recorded.

The procedures are repeated with different loads of weight, w, of 40 N, 50 N, 60 N

and 70 N.

The actual corresponding readings are shown in Diagrams 1.2, 1.3, 1.4, 1.5 and

1.6.

Spring digantung tanpa pemberat pada permulaan eksperimen. Panjang asal

spring, lo= 15.0 cm.
