Springs/Moments Unfinished

Question 1

Hooke’s Law

Answer 1

The extension of a spring is directly proportional to the force applied, provided that the limit of proportionality is not exceeded.

Question 2

The principle of conservation of moment

Answer 2

For an object to be in equilibrium the resultant moment of forces must be zero, about a point.

Question 3

Principle of momemts

Answer 3

For an object to be in equilibrium, the sum of the clockwise moments must be equal to the sum of the anti-clockwise moments.

total clockwise moments = total anticlockwise moments
