Look at the diagram of the cyclist. Which of the following labels for A and B are correct? (N.B. There may be more than one correct answer)
A = Driver B = Input
A = Driven B = Output
A = Driver B = Driven
A = Output B = Input
A = Input B = Output
What is gear ratio equal to?
Gear Ratio = Driven x Driver
Gear Ratio = Driven ÷ Driver
Gear Ratio = Input Speed ÷ Driver
Gear Ratio = Output Speed x Driver
Select the correct memory triangle for calculating gear ratios.
Which of the following memory triangles can be used to calculate gear speeds?
What is output speed equal to?
Output speed = Gear Ratio ÷ Input Speed
Output speed = Input Speed ÷ Gear Ratio
Output speed = Gear Ratio x Driven
Output speed = Driver x Gear Ratio
Describe the types of motion (starting from the driver to the driven) that the cam and follower mechanism gives
(Driver) Linear → (Driven) Rotary
(Driver) Rotary → (Driven) Linear
(Driver) Rotary → (Driven) Oscillation
(Driver) Oscillation → (Driven) Reciprocating
(Driver) Rotary → (Driven) Reciprocating
Which of the following equations can you use to calculate the gear ratio of a compound gear labelled A, B, C, D as shown in the diagram?
What are the correct labels for this lever (tweezers)? Think of the answer, or write it down, before you select one of the choices below.
A = Fulcrum B = Load C = Effort
A = Effort B = Load C = Effort
A = Load B = Effort C = Fulcrum
A = Fulcrum B = Effort C = Load
What class of lever is the tweezers?
Class 1
Class 2
Class 3
What type of motion does the quick return mechanism involve?
Reciprocating → Linear
Reciprocating → Rotary
Rotary → Reciprocating
Rotary → Oscillating
