Explain that students must develop a popsicle bridge from 200 popsicle sticks and glue. The bridge must be able to hold a pre-determined weight 5 pounds or 20 pounds Structure must span a minimum of 14 inches in length.

What is needed to build a truss bridge?

Structurally, Arete Structures truss bridges contains five fundamental elements: Foundation/abutments and piers (for multi-span) Truss. Floor beams and outriggers that connect and support the two trusses.

How much weight can a popsicle stick truss bridge hold?

Mere 100 popsicle sticks can be arranged and glued together into the style of Howe Truss bridge that can by itself carry the weight of over 200 pounds. Large and more elaborate popsicle bridges can withstand the weight of over 3,000 pounds!

How do truss bridges work simple?

In a truss bridge, two long – usually straight members known as chords – form the top and bottom; they are connected by a web of vertical posts and diagonals. The bridge is supported at the ends by abutments and sometimes in the middle by piers.

How do you make an arch bridge with Popsicle sticks?

1. Cut rounded edges off four popsicle sticks so the sticks are 4 inches long, and place them in warm water for five minutes.
2. Cut rounded edges off 68 popsicle sticks so the sticks are 4 inches long.
3. Stack center of the bridge to create the high arch.

What are the 5 main components of a truss bridge?

Structurally, Arete Structures truss bridges contains five fundamental elements:

• Foundation/abutments and piers (for multi-span)
• Truss.
• Floor beams and outriggers that connect and support the two trusses.
• Stringers sit on top of the floor beams and support the decking.
• Decking.

How do you make a strong Popsicle Stick bridge?

Cut four popsicle sticks in half. Place each of the halved popsicle sticks at both ends of each of the truss beams, in the middle position of the three-wide popsicle sticks. The component three-wide popsicle sticks of each truss will be glued together to form a truss three sticks thick.

How does a truss work?

Trusses are most commonly used in bridges, roofs and towers. A truss is made up of a web of triangles joined together to enable the even distribution of weight and the handling of changing tension and compression without bending or shearing.

What is the best design for a popsicle stick bridge?

Practice will make you better.

Measure twice and cut once.

Don’t use too much glue.

Humidity can change the weight and durability of the bridge.

Dirty hands can apply skin oil or grease to the glue joints.

Lateral bridge twists can be prevented with lateral bracing.

Read the glue instructions to learn its optimal use.

How to build the strongest popsicle stick bridge?

Clip two popsicle sticks together end to end using a binder clip.

Hold one end of each popsicle stick in each hand.

Now make a square out of popsicle sticks that are connected by binder clips at the four corners.

Grip two adjacent popsicle sticks with your fingers and gently try to rotate them relative to the joint that connects them.

How do you build a popsicle stick bridge?

How do you build a bridge out of Popsicle sticks step by step? Cut one stick in half using a large scissors. Glue the halves to each end of the 3 sticks placed end to end and glue two popsicle sticks in the middle. Glue three more full sticks on top to create three layers with overlapping joints.
