Forces Flashcards
What are moments measured in
Newton Metres Nm
What is the turning effect of a force
A moment
What is a moment
The turning effect of a force
Moment equation
Moment=Force x Distance from pivot
What is pressure measured in
Pascals (Pa) or Newtons per square metre (N/m2)
Pressure equation
Pressure=Force/Area
What happens to pressure when the liquid gets deeper
In increases
What is the first part of the hydraulic calculation
Pressure=Force Applied/Area of master piston
What is the second part of the hydraulic calculation
Force exerted=Pressure x Area of slave piston
What is the whole hydraulic equation
Pressure=Force Applied/Area of master piston
Force Exerted=Pressure x Area of slave piston
Which piston is bigger
The slave piston is bigger than the master piston
What causes atmospheric pressure
The weight of air particles pressing down on the ones underneath
What happens to the pressure when a force is spread over a large area
It will be lower than a small area
How to increase the pressure in solids
Increase the force or decrease the area
Speed equation
Speed=Distance/Time
