Engineering Design Quiz

Which of the following best describes a constraint in engineering design?

• A material used in the project

• A limitation that affects the design

• The number of team members

• The overall project cost

The mechanical advantage of a simple machine is calculated by:

• Dividing effort by load

• Multiplying effort and load

• Dividing load by effort

• Subtracting effort from load

If a gear ratio is 2:1, what does it indicate about the gears?

• The larger gear rotates twice for every rotation of the smaller gear

• The smaller gear rotates twice for every rotation of the larger gear

• Both gears rotate at the same speed

• The gears are not moving

How is power calculated in a mechanical system?

• Work ÷ Time

• Force × Distance

• Load ÷ Effort

• Speed × Gear Ratio

In an electrical circuit, the current (I) can be calculated using Ohm's Law as:

• I = R × V

• I = V × R

• I = R / V

• I = V / R
