For example, this could be a door opening around a fixed hinge or a spanner turning around a fixed nut.]]> 2016-08-22 11:13:52 UTC https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119123480 The size of a moment depends on two factors bhyat_d_219 https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119123705 1. The perpendicular distance from the pivot to the area of the force.
2. The size of the force applied.

The fixed point is called the pivot or fulcrum. Moments can act in two ways: Clockwise or Anticlockwise]]> 2016-08-22 11:19:30 UTC https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119124076 Equation bhyat_d_219 https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119124262 We define the turning effect with the equation:
Moment(Nm) = Force(N)× Perpendicular distance from the pivot(m)
moment = F × d]]> 2016-08-22 11:21:06 UTC https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119124262 In Balance bhyat_d_219 https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119547651 An object will be in balance if : sum of anticlockwise moments = sum of clockwise moments. The clockwise and anticlockwise moments on the crane must be balanced.]]> 2016-08-24 10:19:38 UTC https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119547651 Clockwise and Anti-clockwise movements bhyat_d_219 https://padlet.com/bhyat_d_219/53h6p3xk2z2n/wish/119548333 A see-saw has a pivot in the middle:
  • the person on the right exerts a force downward - which causes a clockwise moment
  • the person of the left exerts a force downward - which causes an anti-clockwise moment
If the people are identical weights and sit identical distances from the pivot, the see-saw will balance. This is because the total clockwise moment is balanced by the total anti-clockwise moment.
The see-saw can still be made to balance even if the people are different weights. To do this, the person with the bigger weight must sit closer to the pivot. This reduces the size of the moment so the opposing moments are once again balanced.
