6.2- BALANCED FORCES Flashcards
1
Q
When two forces act on a point object, when is the object in equilibrium?
A
if two forced are equal and opposite to each other
2
Q
If an object is in equilibrium what is the resultant force?
A
zero
3
Q
If an object is in equilibrium, what are the two forces described as?
A
balanced
4
Q
What is weight equal to?
A
support force
S=W
5
Q
when three forces act on a point object, when is their combined effect zero?
A
if the resultant force of two of the forces equal and opposite to third force
6
Q
How can you check the combined effect of three forces in zero?(2)
A
resolve each force along the same parallel and perpendicular lines
balance components along each line
