Eduqas DT section 4

What is motion?

• A force that pulls objects together

• An object moving its position over time

• A mechanism that controls forces

• A system that produces output force

How is force measured?

• In kilograms (kg)

• In meters per second (m/s)

• In newtons (N)

• In revolutions per minute (rpm)

What does a mechanical system do with an input force?

• It stops the force

• It ignores the force

• It produces an output force

• It measures the force

What type of motion follows the path of a circle?

• Linear

• Oscillating

• Reciprocating

• Rotary

Which type of motion is described as back-and-forth in a straight line?

• Rotary

• Linear

• Oscillating

• Reciprocating

What is the primary function of a lever in a mechanical system?

• To convert rotary motion to linear motion

• To control and change motion

• To increase speed

• To decrease friction

What is a spur gear?

• A gear with a smooth surface

• A gear with teeth around the edge

• A gear with a flat surface

• A gear with a spiral shape

What happens when a smaller gear turns a bigger gear?

• The smaller gear stops

• The bigger gear turns faster

• It's called a pinion

• The gears rotate in the same direction

What is the function of a cam and follower in a mechanical system?

• To convert linear motion to rotary motion

• To change rotary motion to back-and-forth motion

• To increase speed

• To decrease force

What is the purpose of a belt drive in a mechanical system?

• To change direction of motion

• To separate input and output shafts by a greater distance

• To convert linear motion to rotary motion

• To decrease speed
