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

How does calculating power in a mechanical system help in evaluating its efficiency?

How does understanding gear ratios help in designing mechanical systems?

Why is calculating mechanical advantage important in engineering?

Explain how mathematics is used to evaluate engineering solutions.

Compare the advantages of a parallel circuit to a series circuit.
