ASTB Formulas Exam with Complete
Solutions
F^e= FL * dl/d^e
OR
F^e * d^e = FL * DL
F^e= effect force
FL= force load
dL= Distance from load to fulcrum
d^e= Distance from effect force to fulcrum - ANS-Formula to find the force of a lever?
Volts X Amps = Power - ANS-Formula for power
(2*Pi*r*h) + (2*Pi*r^2) - ANS-Formula for area of a cylinder?
Work in/Work out
Note: never more than 1. - ANS-Formula for efficiency?
I=V/R
I= current
V= Volts
R= resistance (ohms) - ANS-Formula for Ohm's law?
Density/ ref. density. - ANS-Formula for relative density?
Mass X Acceleration = Force - ANS-Equation for force?
A = 4*Pi*R^2 - ANS-Formula for area of a sphere?
Skin friction drag + Form drag = Parasitic drag. - ANS-Formula for parasitic drag?
Force X Distance = Work - ANS-Equation for work?
Effort arm/ resistance arm - ANS-Formula for mechanical advantage of a lever?
Mass/ Volume - ANS-Formula for density?
