Mechanisms!

What is another name for output?

• Drive
• Driven
• Torque 
• Speed

What is Torque?

• A push or pull
• A push or pull in a straight line
• A push or pull in a circular direction

What is Force?

• A push or pull
• A push or pull in a circular direction
• A push or pull in a straight line 

What is the relationship between torque and speed?

• Speed is constant, torque is constant
• Torque increases, speed decreases
• Speed increases, torque decreases
• All the above

What is the gear ratio for a straight gear train where the input gear rotates 8 times while the output rotates 12 times

• Gear Ratio= 2 to 3
• Gear Ratio= 4 to 6
• Gear Ratio= 3 to 2
• Gear Ratio= 6 to 4

Which of the following is not true about mechanisms? 

• They can change the speed of movement
• They can change the direction of movement
• They can change the torque of movement 
• They can change the material of movement

Oscillation is?

• Continuous movement in a straight line
• Movement at the end of a spring
• Another name for reversible direction
• Movement similar to a pendulum

Reciprocation is? 

• Continuous movement in a straight line
• Back and forth movement in a straight line
• Another name for reversible direction
• The gear ratio in a worm gear train

Worm gears have outputs that have:

• Higher speed and higher torque
• Lower speed and lower torque
• Lower speed and higher torque
• Higher speed and lower torque 

Universal joints: 

• Can change the speed of movement 
• Can change the force of torque
• Can change the angle of movement 
• Connect brackets to metal plates
