Engineering and Physics Concepts Quiz

What is Ohm's Law used to calculate?

• Mechanical advantage

• Resistance, current, and voltage

• Velocity ratio

• Scale factors

How is the mechanical advantage (MA) of a system calculated?

• MA = Effort/Load

• MA = Load/Distance

• MA = Load/Effort

• MA = Distance/Load

What does the velocity ratio (VR) of a mechanism require?

• The weight of the load

• The speed of the effort

• The distances moved by the load and the effort

• The time taken by the load

Which units are used for giving sizes on engineering drawings?

• Pounds and pence

• Hours and minutes

• Millimetres and metres

• Inches and feet

What is the purpose of hidden detail lines in engineering drawings?

• To show visible surfaces

• To represent three-dimensional objects

• To show surfaces not directly visible

• To clarify the interior construction
