State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

We romped until the pans Slid from the kitchen shelf; My mother ’s countenance Could not unfrown itself.
