1. Equations for WORK
WORK = force * distance
2. Efficiency of work
Work out / Work in
3. Pressure Equation
Pressure = force applied / area

in a hydraulic pressure system, hydraulic pressure is constant while area is the variable that will change
4. Three ways heat transfer
• 1. conduction
• 2. convection

• heat moves from hot to cold
• the larger the difference of heat transfer the faster heat is moving
5. series circuit and christmas tree lights
if one light goes they all go
6. Torgue equation
torque = force * distance

MA = Effort arm / resistance arm
8. shallow slope
provides a better M.A

slope length/ slope height = M.A
9. Pythagorean Theorem
a^2 + b^2 = c^2
10. area of a triangle
A = 1/2 bh
11. Volume
V= l*w*h
12. area of a circle
A= pie r^2
13. circumference or perimeter of a circle
pie * diameter

14. volume of a cube
V = sides ^3
15. Volume of a cylinder
V= pie * radius square * height
16. y = mx + b
m = slope which is rise / run

b is intercept
17. gears
(revolution of gear A) (teeth of A) = revolution of gear B) (teeth of gear B)
