Understanding Snapback Severity
Просмотров 5928 месяцев назад
When designing snapback arresting systems to help keep people safe on berths, it's important to understand how severe snapback events can be. A snapback event is when a mooring line snaps under tension. Parted lines can travel up to 1000 km/hr in less than 0.5 seconds.

Its because the laver and wood was old and well knocked while the gray nicolls was pretty much new and the difference was pretty marginal.
well it dont really matter if the pole stood up or not because the pole moved several feet and snapped the wires or broke off the insulators
thats called momentum
It isn't safe !
Yes, that pole flexed dangerously and snapped the electric conductors. They need to beef up those poles!
WTF?
CA has best bat's specially if you are aggressive batsman for big bang hitting.
From a scientific experiment's point of view, the independent variable appears to be the mass of the bat (in grams) and the dependent variable the speed of the ball leaving the bat after the impact (in km/h), but in order to obtain a fair test, the control variables also needed to be taken into account, such as length of the bat, the speed and point in which the swinging arm is released, the initial position of the ball, which were all being taken good care of. However, one important characteristic of the willow, being a natural material, is neglected, which is the density of the wood, and the amount of intact air pockets under the harden surface of the bat. Therefore it isn't going be easy to draw a conclusion based on this test. In fact, I don't know how one can ensure the amount of ping (caused by the air pockets in the willow) can be controlled to conduct a fair test. I guess if we include the mass of the bat as a control variable, make the thickness of the bat as an independent variable instead, we might be able to test thick vs thin instead of mass, as a thick bat isn't always a heavy one also. Just my humble opinion.
Kooookapura is the worlds no'1cricket bat
It's kookaburra
Jeez Aidan is that your good Laver and Wood Bat ... ?
Kookabura is best bat
Excellent experiment but here we are trying to see which shape is better. To find that out, it would be better if different generation bats were of same weight and the swing speed is kept the same (I know this might be difficult with the setup though but could be attempted). Then the ball speed going off the bat will tell us the winner in terms of the shape. Otherwise, we don't know the winner as the heavier bat/faster bat could be better performing despite bad shape.
this was a great idea however I think that the sweetspots were different on all bats which may have lead to an inaccurate measurement
these bat makers have killed cricket
how? u expect the bats to be the sam as the 99s the world upgrade every year the next 5 years the bats going to be way better than what they are using today
+Jermylee Barnett - We agree. The fact that bats have improved, and will improve further is a given. We were simply trying to understand how much better bats have got. No one had ever tried to quantify it so we thought we should give it a go.
+Holmes Solutions i understand that but i dont understand how this guy saying these type of bats today killed cricket like he expect the bat to be the same as in the 90s
Jermylee Barnett Because you dont understand Cricket
+Jermylee Barnett if i'm not wrong what @Flint is referring to is that bats were made to drive the ball and not hit it with force. By giving extra wood and lower sweet spot they're promoting power play in cricket more than technique. Try driving the ball through the gully with these thick edge and low sweet spot bats and you'll know the difference.

Where in the world are you guys based? sounds like the UK.
Aarif Ellemdeen We are located in Christchurch, New Zealand.
Thats really the otherside of the world. Unfortunately don't know much people there otherwise would of tried to help you guys out to secure some bats.
Aarif Ellemdeen Thanks for the thought. We've got Laver & Wood based here in New Zealand, and Kookaburra just next door. Who else would you want to see in the cricket bat mix?
The brands don't really make a difference, the most important thing would be the profile. If you come to thing of it once you take off all the stickers from a bat how to you know what exactly it is. So brands not important. Another fascinating topic is players willow vs. lower grade english willow fascinates me. If by chance you get the same density clefts grade 5 and pro grade willow. Get one guy to make exactly the same profile and press both bats to peak performance, then look if players grade is better than lower grade. Manufacturers will hate this LOL
+Aarif Ellemdeen I agree with the last suggestion. You guys should do that experiment and see what the difference is between Players grade vs Grade 2/3/4.
Would love to see the the effect of the increase in edge size of the cricket bats on the speed of the ball. So instead of hitting the ball in the middle try hitting it off centre, maybe like about 2-3cm from the edge. Just to see if scollop bats perform better than the full profile counterparts. Would also take out a few variables like the difference in weight. 3 bats all 3 the same weight. All prepared in the same manner, all three having different profiles. The first like that old kookabura, the second like a scolloped bat and the 3rd a nice full profile with a decent edge size.
Aarif Ellemdeen - Great suggestion, and one we would love to explore if we can find a bat manufacturer to provide us the bats to test. You are quite right that there were a few too many variables to call this test truly scientific. It was really just a bit of fun in the lab. If you know anyone who is happy to provide the bats, we will happily do the test.
