Forces, moments and equilibrium Flashcards
1
Q
What does force cause?
A
A force causes translational acceleration of a mass
2
Q
What is the equation for horizontal force?
A
3
Q
What is the equation for vertical force?
A
4
Q
What is the equilibrium for particles?
A
A particle is in equilibrium when it has a zero resultant force acting on it (i.e. zero magnitude), which means a zero horizontal force component AND a zero vertical force component
5
Q
If F = 20kN at an angle of 30 to the horizontal, what will the force components be?
A
6
Q
How do you work out force using pythagoras?
A
