A balance and torque experiment is conducted with an UN-balanced ruler.

Length of the ruler: 1 m

Mass of the ruler: 149 g

The pivot is at the 32-cm mark.

A 77-g mass is located at the 24-cm mark of the ruler.

We want to balance the ruler by placing another mass at the 11-cm mark.

What should be magnitude of this additional mass?

A balance and torque experiment is conducted with an UN-balanced ruler.

Length of the ruler: 1 m

Mass of the ruler: 97 g

The pivot is at the 61-cm mark.

A 45-g mass is located at the 33-cm mark of the ruler.

We want to balance the ruler by placing a 207-g mass somewhere on the ruler.

At which mark on the ruler should we place the 207-g mass?

The formula for length contraction gives the length of an interval on a ruler moving with velocity v relative to an observer as where L is the length of the same interval on a ruler at rest with respect to the observer. By what fraction is the length of a meter stick reduced if its velocity relative to you is measured to be 87 percent of the speed of light?

A steel ruler (100 mm) is used for measuring the length of a block. The ambient temperature is found likely to vary in between 24 °C and 25 °C. The temperature is likely to be anywhere within these limits. The temperature variation follows square distribution, with expected value to be 24.5 °C. Determine the degree of uncertainty that will be registered when measurement is done using steel scale? CTE = 11.5 x 10-6 / °C
