Slide 1:

Pressure and Moments

Slide 2:

Pressure - In solids If a force is applied over a smaller surface area you get a larger pressure. Pressure can be calculated using the following equation: Newtons N Pascals or N/m 2 m 2

Slide 3:

Pressure increases with depth. Pressure acts equally in all directions. Pressure is transmitted through liquids. Pressure - In liquids All hydraulics systems work because the pressure is the same throughout the system.

Slide 4:

Moments Moments make things turn or rotate. They are caused by forces but are not forces themselves. The moment will be bigger if: The force causing the turning effect is bigger. The force is further from the pivot.

Calculating the size of a moment :

Calculating the size of a moment Moment = Force x Distance Newtons N m Nm

Slide 6:

Anti-clockwise Moment = Clockwise Moment BALANCED Net moment is zero
