Do you have to wear a safety helmet when driving a motorcycle?
These functions can reduce the impact force of about 1850 kilograms, so the actual impact on the head is only about 400 kilograms. In addition, the safety helmet in bold colors, while meeting or overtaking, can cause the other member's attention. So how important is the safety helmet?.
Because the helmet is smooth, hemispherical, the impact force can be scattered and absorb impact force, and the helmet deformation or cracks, and pads also play a buffer role, but also absorb part of the energy. According to estimates: People's head can generally withstand 450 kilograms of impact force.
A contest was held in 1956 in California, a famous player William Snell in the game. After that, the relevant research institutions in the United States regard the design of safety helmets as the key research projects. After repeated experiments, experts demonstrated that the head was hit violently when it happened, and that the helmet could protect the head effectively.
