At the low impact force level of 3 J (12 cm drop height
), the K[R] and A[R] brands of hand and foot protectors reduced the impact below the stated threshold of 2000 N, but at the higher impact levels, they did not perform effectively.
Logistic regression modeling in R software was used to determine whether there is a relationship between drop height
and the probability that a crab died within 5 d of holding, and whether any other variables influenced the likelihood of survival, including 1) the November 2013 vs.
The impact sensitivities of the six types of Al-PTFE specimens were calculated by the characteristic drop height
([H.sub.50]), at which the specimen can react with a 50% possibility.
These pounders are identical in terms of material, mass density, Young's modulus, Poisson's ratio, volume, mass, and drop height
from the water surface.
Each drop height
corresponded to a treatment: 0 (control), 1, 2, 3, 4 and 5 meters, totaling six treatments.
of nanococrystal explosive increased by 31.9 cm compared with CL-20/HMX mixture, and explosion probability of friction was 20% lower than that of raw HMX.
The present model has been used to evaluate the ignition probability of explosive particles under drop height
. The size and distribution of the particles are investigated by Laser Particle Size Analyzer Malvern MS2000 before experiment and calculation.
Limit Analysis Based on the Finite Element Model of the Egg
* Impact energy--max lump weight (lb.) x drop height
(ft.) up to 250 lb.-ft.
Results indicate a drop height
of approximately 19 inches onto a rigid surface will generate ATD lumbar loads of 1500 lbs, whereas drop heights
of 42 +/- 10 inches were required to produce equivalent lumbar loads with a cushion present.
If participants are shown instances of the Newton's cradle with systematic variations of the launcher's drop height
and chain's length and asked to indicate how high they would expect the last ball in the chain to reach, the results can be directly confronted with the normative model.
Military Drop Standards, which limit the drop height
to 1.22 meters while the Big Bang shell can survive 1.4 meter drops.
