Engineering design process
- 2. PROBLEM STATEMENT • All helmets attempt to protect the users head by absorbing mechanical energy and protecting against penetration.Their structure and protective capacity are altered in high -energy impacts . • Beside their energy -absorption capacity,their volume and weight are also important issues,since higher volume and weight increases the injury risk for the users head and neck. • Wearing an appropriate safety helmet significantly reduces the risk of injury or even death.Protective headwear could save your life .
- 3. NEED STATEMENT • Riding a motor cycle gives riders a sense of freedom on the open road however,there sre serious dangers involved in riding without a helmet. • A motor cycle doesnot provide the structural protection that a car does to keep drivers safe in the evevt of an accident. • Motorcyclists need to take extra precautions to protect their body .The most important place to start is by protecting the head. • The head and brain is most vulnerable to injury in a motorcycle accident.Drivers and passengers wearing helmets increase their chance of survival significantly over non-helmet wearers.
