Question

what is the weight shown on the spring scale? remember, you should read the weight displayed at the top of the plunger. n 0 10 20 30 40 24 n 16 n 14 n 26 n

Explanation:

Step1: Identify scale intervals

The scale ranges from 0 - 40 N. There are 4 intervals between 0 and 40, so each interval is $\frac{40}{4}=10$ N. And each small - sub - interval is $\frac{10}{5} = 2$ N.

Step2: Read the value

The top of the plunger is at the 3rd small - sub - interval above 10 N. So the value is $10+3\times2=16$ N.

Answer:

16 N
