FORT WAYNE, Ind. (Indiana's NewsCenter) - In this week's episode of Cool Science Monday, Martin Fisher from Science Central talks about the annual Bridge Building Competition on 2/19.
Middle school and high school kids build bridges from popsicle sticks. Judges from the IPFW Engineering Department will place the bridges in a machine and apply pressure until the bridge breaks.
A bridge can be made to be stronger by adding triangular-shaped sections called trusses.
Martin also shows off another type of bridge, with a curved shape called a catenary arch. The block at the top, called the keystone, supports the left and right side of the bridge and holds the shape. If it's removed, the bridge falls.
