• Neither A nor B

If an object has a mass of 10 kg and a volume of 2 cubic meters, what is its density?

• 2 kg/m³

• 5 kg/m³

• 20 kg/m³

• 0.2 kg/m³

What is the primary role of quality control in engineering?

• To ensure processes and products meet specifications

• To identify and discard defective products

• To improve efficiency through lean practices

• To train workers in quality standards

Which practice can significantly reduce waste in quality management?

What is the primary purpose of a clinometer in engineering?

• To measure slopes and angles

• To calculate distances

• To gauge torque

• To evaluate material stress

Why are digital measurement tools favored over analog ones?

• They are more cost-effective.

• They provide faster and more accurate results.

• They eliminate the need for calibration.

• They work without external power.

What distinguishes a first-class lever from other types?

• The fulcrum is located between the load and the effort.

• The load is closer to the fulcrum than the effort.

• The effort is applied between the load and the fulcrum.

• It reduces distance instead of force.

How does increasing the number of rope segments in a pulley system affect its mechanical advantage?

• Increases the mechanical advantage

• Reduces the efficiency

• Increases friction

• Decreases the required effort
