Truss Basics and Static Determinance

What is the primary shape used in trusses to ensure stability?

• Square

• Circle

• Triangle

• Rectangle

Which type of support prevents motion in all directions?

• Pinned support

• Sliding support

• Roller support

• Fixed support

What is the function of a roller support in a truss?

• Prevents motion in all directions

• Allows motion in one direction

• Provides no support

• Supports only vertical loads

What are the points called where truss members meet?

• Joints

• Connections

• Nodes

• Vertices

Which color is used to represent tension forces in trusses?

• Yellow

• Green

• Red

• Blue

What is the first step in evaluating a truss?

• Assessing material strength

• Measuring joint angles

• Identifying static determinants

• Calculating member forces

Which assumption is made about the weight of truss members?

• They have variable weight

• They have constant weight

• They have no weight

• They have significant weight

What does the equation 2J = M + R help determine?

• The color of the truss

• The stability of the truss

• The weight of the truss

• The length of the truss

Why is flexibility important in truss structures?

• To allow reaction to forces

• To prevent movement

• To reduce cost

• To increase weight

In the Brockport bridge example, how many reaction forces are present?

• Five

• Four

• Three

• Two
