Moments

Which is the equation for calculating moments?

• Moment = Force x Distance moved

• Moment = Mass x Perpendicular Distance to pivot

• Moment = Force x Perpendicular Distance to pivot

• Moment = Force x Distance to pivot

The units for moments are...

• Newtons (N)

• Metres (m)

• Newton Metres (Nm)

• Newtons per Metre (N/m)

'Perpendicular to' means...

• Parallel to

• At 90^o to

• Next to

• Alongside

When object's balance, the moment clockwise and anticlockwise must be..

• Equal

• Zero

• Large

• Small

The weight of the barrel is (a)   N

The mass of the barrel is (a)   kg

(assume we are on Earth where 100g has a weight of 1N)

Which allows the crane to lift a heavier load?

• Move the hook closer to the pivot

• Move the hook away from the pivot

• Increase the counterweight

• Decrease the counterweight

• Move the counterweight further from the pivot
