actuator: 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).

Examples

bplot(actuator$force,by=actuator$act)
lplot(actuator$act,actuator$force,actuator$press)
anova( lm(force ~ (act+press+nozzle+line)^2, data=actuator) )
