rigid bodies

Question 1

rigid bodies take into account…

Answer 1

rotation of the body, size of the object

Question 2

moments in equilibrium

Answer 2

clockwise moment = anti-clockwise

Question 3

what is the moment of a force

Answer 3

measures the turning effect of the force on the body on which it is acting

Question 4

moment of a force =

Answer 4

force x distance ( PERPENDICULAR DISTANCE)

Question 5

if a rigid body is in equilibrium,

Answer 5

• the resultant force in any direction = 0 , so forces up = forces down (y1)
• the resultant moment about any point is 0 ( clockwise moment = anti-clockwise moment)

Question 6

what does uniform mean?
where does weight act on a uniform body

Answer 6

• mass spread evenly
• weight acts on the centre
