Mechanical Control Systems

What are the different types of motion in mechanical control systems?

• Linear motion and Rotary motion

• Oscillatory motion and Random motion

• Translational motion and Vibrational motion

• Circular motion and Projectile motion

Explain the function of a Class 1 lever in mechanical control systems.

• A Class 1 lever amplifies force by balancing the load and effort around the fulcrum.

• A Class 1 lever reduces friction in mechanical systems.

• A Class 1 lever is used to change the direction of motion in mechanical systems.

• A Class 1 lever is primarily used for speed regulation in mechanical systems.

A Class 2 lever is characterized by:

• the fulcrum is between the effort and the load

• the load is between the fulcrum and the effort

• the effort is between the fulcrum and the load

• the fulcrum and load are at the same point

A Class 3 lever is used in mechanical control systems. Which of the following best describes its function?

• It multiplies force.

• It changes the direction of force.

• It increases speed and range of motion.

• It balances forces.

Cams and followers are components in mechanical systems. What is their primary function?

• To convert rotary motion into linear motion

• To store energy

• To increase speed

• To reduce friction

How do pulley and belt systems work in mechanical control systems?

• By transferring rotational motion between shafts

• By converting electrical energy to mechanical energy

• By storing energy for later use

• By reducing friction in moving parts

What role do gears play in mechanical control systems?

• Gears are used to increase speed.

• Gears are used to decrease speed.

• Gears are used to transmit torque and change the direction of motion.

• Gears are used to store energy.

The role of mechanical devices in terms of force is to:

• increase force

• decrease force

• change the direction of force

• all of the above
