Design of Safe Ski/Snowboard Jumps #8

Open moorepants opened 4 years ago

moorepants commented 4 years ago

Description

Recreational skiers and snowboarders are regularly injured on jumps. Ski resorts construct these jumps with little to no design. The jumps can be designed to be safer. For example, jumps designed with a constant equivalent fall height that is small are likely safer than those with large equivalent fall heights.
