In the early days of baseball, players caught the ball with their bare hands. Back then, gloves were for beginners. But broken bones have a way of changing people's minds. In 1875, Charlie Waite shocked spectators when he wore a leather mitt, playing first base for the St. Louis Brown Stockings. And so the baseball glove was born. In the decades, athletes have become stronger, bats hit harder and balls fly faster, so the glove has had to evolve to prevent fractured fingers.

Computer modeling allows Joseph to predict exactly how the pole will react when a 79 kg athlete plants it into the ground at nearly 40 km an hour. The design is constructed out of layers of glass and carbon fiber that start out on rolls. Our process starts with an engineering drawing. This outlines the specs of the pole such as the length and the materials used. Now that we have all the dimensions we need, we can come over here and have our material ready.
The word “dimensions” in this sentence is close in meaning to…
sizes
scopes
ranges
extensions

The trickiest part of the design is making sure the pole bends properly. Where and how much it bends is down to a central section known as the sail. As the vaulter runs, they build up kinetic energy. The pole deforms when it's planted into the ground, briefly storing this energy. The pole then releases the stored energy, converting it into maximum height.
