Actuator force experiment
Description
Small propulsion units, called actuators, are used to maneuver space craft once they are in space. In order to control these motions accurately, the actuator needs to produce a precise amount of force. This data set represents an experiment to understand what factors effect the variability of the force produced by an actuator. The actuator is fired using compressed air, and the factors studied are the actuator used (act), the amount of pressure used (press), the length of the air supply line (line) and the nozzle type (nozzle).
Format
A data frame with 16 observations on the following 6 variables.
- act
actuator used (A1 or A2)
- press
amount of pressure used (30psi or 100psi)
- line
length of the air supply line (20ft or 40ft)
- nozzle
nozzle type (rightang or straight)
- force
force produced
- order
experimental order
