Belt Damage," Wear, Vol. 318, pp. 145-152.

Description: Experiment to determine whether a dropped item caused significant
damage to a conveyor belt (Y=1 if yes, 0 if no). Data approximated from Figure 6 (pyramid impactor).
Factors: 
X1 = Height of dropped item (meters)
X2=1 if Belt is New (0 ow), X3=1 if Belt is Renovated (0 ow), Reference=Worn (X2=X3=0)

Variable Names:
degDam  (Degree of Damage, 3 or 4 => significant damage)
belt  (1=New, 2=Renovated, 3=Worn)
height   (meters)
