moments Flashcards
1
Q
what’s the definition of moments
A
measure of rotation around a point (pivot)
2
Q
what’s the moments equation?
A
moment (Nm) = perpendicular distance to force x force
3
Q
how do you calculate the resultant moment?
A
sum + of all moments, clockwise minus anticlockwise
4
Q
how do you determine the overall direction of a resultant moment?
A
the sign whether its negative or positive
5
Q
what does a negative resultant mean
A
anticlockwise movement of the body
6
Q
what does a positive resultant mean
A
clockwise movement of the body
7
Q
what is meant moments are in equilibrium?
A
anticlockwise moments = clockwise moments
8
Q
how do you solve to find missing values in an equilibrium moment
A
using the fact that the resultant moment at any point is 0 Nm
