number of teeth on pinion ÷ number of teeth on rack per meter x 1 metre
1 of 12
Efficiency
efficiency = mechanical advantage ÷ velocity ratio x 100
2 of 12
3 of 12
Velocity Ratio
velocity ratio = distance moved by effort ÷ distance moved by load
4 of 12
Distance Moved by Effort
distance moved by effort = distance moved by load x velocity ratio
5 of 12
distance moved by load = distance moved by effort ÷ velocity ratio
6 of 12
Volume of a Sphere
volume = 4/3πr^3
7 of 12
Volume of a Cone
volume = πr^2h ÷ 3
8 of 12
Volume of a Regular Square Pyramid
volume = 1/3 x base x length // area of base = length^2
9 of 12
Volume of a Cylinder
area of circle = πr^2 // circumference = 2πr // volume = πr^2h
