Comparative Impact Tests on Helmets
Comparative Impact Tests on Helmets

9/2/2005, · The height ,of the helmet impact, point from the anvil surface was constant at every drop test: 2000 +/- 3 mm. The anvil surface was flat. Additionally between the flat surface and the 550 kg mass of base was placed a special ,force, transducer,

Bicycle Helmets: What are their limits?
Bicycle Helmets: What are their limits?

The typical bicycle crash ,impact, occurs at a ,force, level equating to about 1 meter (3 feet) of drop, or a falling speed of 10 MPH. The rider's forward speed before the crash may be considerably higher than that, but the speed of the head closing with the ground, plus a component of the forward speed, less any energy "scrubbed off" in other ways, normally average out at about 10 MPH.
