What's are 3 precaution of moment and Archimedes principles
Answers
Answer:
The Principle of Moments states that when a body is balanced, the total clockwise moment about a point equals the total anticlockwise moment about the same point.
Equation
Moment =force F x perpendicular distance from the pivot d.
Moment = Fd
Apparatus
A uniform metre rule, retort stand, boss and clamp, two 100 g mass hangers and 12, 100g slotted masses, a g-clamp, three lengths of string.

Method
Suspend the metre rule at the 50 cm mark so that it is balanced horizontally. The ruler is said to be in equilibrium. The 50 cm mark is the pivot.
Suspend a mass, m1, from one side of the ruler a distance, d1, from the pivot. Read the distance d1 in cm, from m1 to the pivot. Record in a suitable table. Record the value of mass m1 in kg in the table too.
Suspend a second mass, m2, from the other side of the pivot. Carefully move this mass backwards and forwards until the ruler is once more balanced horizontally. Read the distance d2 in cm from the mass m2 to the pivot. Record d2 in cm, in the table, along with the mass m2 in kg.
Repeat several times using different masses and distances.
Calculate the turning forces, F1 and F2, using W = mg.
