Haha, yeah, Chuck Norris, and make the tyres of Mr T - you'll never get a puncher but will recieve a lifetime supply of snickers bars.


Rubber? Unless you want one material for the whole thing - bar and grips? Then manybe something GPR like? Not really very soft, unless you could impregnate the GPR with some kind of rubberised plastic like there are on some mobile phones? If you know what I mean?

I'd suggest my mum's cooking, but that's hardly suitable for bike handles. Definately tough enough though...

..thankyoouuu


em..now theres another part to the Q...

Provided the force in the spring is 112.5N and the energy storedin it is 5.06J...The mass of a child is 30kg. Calculate the childs weight and discuss how this new design could reduce the seriousness of an injury (The questions about the making of a new bicycle handle grip as often serious injuries occur as a result of upturned handlebars......help pleease...?

Well if the mass of the child is 30Kg. Surely you just multiply that by gravity, which is ~10 (9.81 to be exact I think). So the child should weigh about 300N, no?

I'm well and truly lost after that...

Where is the spring? What is the new design?

Weight of child=mass *gravity = 9.81*30 = 300 ish N.
