100
This is a working model used to test a design concept by making observations and necessary adjustments.
What is a Prototype?
100
This is a diagram showing all the forces acting on an object, the force's direction and its magnitude.
What is a force (free) body diagram?
100
This is how much a structural member displaces when a force is applied to it.
What is Beam Deflection?
100
This part of the Design process is where you brainstorm solutions to your problem.
What is Generate Concepts?
100
A vector has this and this.
What is magnitude and Direction?
200
This enables engineers to quickly and easily modify the dimensions of parts without needing to redesign or re-dimension the entire object for every size.
What is Parametric Modeling?
200
In the diagram below, the net force would be this and the direction the object would travel would be this.
What is 15 N and up?
200
A structural member will do this if it deflects too far.
What is it will break?
200
When choosing a solution, the group will create one of these to judge the designs and pick the best one.
What is Decision Matrix?
200
The moment of an object is dependent on these two things.
What is force and distance?
300
This is any set of physical properties whose values determine the characteristic or behavior of something.
What is a parameter?
300
Look at the vector presented below. This would be the x and y components of the vector.
What is 14.99 ≈ 15 for both x and y component?
300
In the equation for beam deflection as shown below, the variable E represents this.
Delta=(FL^3)/(3EI)
What is the Modulus of Elasticity?
300
The first step in the design process is to do this.
What is Define the Problem?
300
A moment produces a counter-clockwise rotation meaning that it is this.
What is positive?
400
This type of chart is used to display each step of the design process, how long each step will take and who is completing it.
What is a Gantt Chart?
400
Look at the vector presented below. This would be the x and y components of the vector.
What is x = -11.95 ≈ -12 and y = -10.03?
400
The moment of a inertia for a 10"x6"x3' is this. (Keep your answer in in4 and assume we are laying the board on the 6" side)
I=(bh^3)/12
What is 500 in4?
400
This is a clear and concise identification and description of the design problem or opportunity.
What is a problem statement?
400
We put a pin at point A in the diagram below. The force Ray would produce this kind of rotation. 
What is no rotation will occur?
500
This is the dimension that will work 99.9% of the time when looking at tolerance calculations.
What is the Root Sum Squared (RSS) Max?
500
In the diagram below, this would be the length and direction of the resultant of the vectors being added together.
What is 9.22 long and an angle of -40.9(320)?
500
A force of 180lbs is applied to a Douglas Fir with dimensions 5"x2"x10'. This is how much the beam deflects. (E = 1.33x106 Psi and assume the board is laying on the 2" side.)
Delta = (FL^3)/(3EI)
What is 3.7 in?
500
These are the limits on the design and production of a product, expressed with specific, measurable values. These might include time constraints, budget, codes, safety, or physical attributes (size, weight, color).
What are Constraints?
500
To determine if a truss system can be solved mathematically, we need to know these three things.
What is the number of joints, members, and reaction forces?
