• Wedge

Which gear type is most suitable for transmitting motion between perpendicular shafts?

• Spur gear

• Helical gear

• Bevel gear

• Worm gear

What is the purpose of a pulley system?

• To change the direction of the applied force

• To increase the speed of the load movement

• To store energy

• To convert rotational motion into linear motion

A screw is essentially which type of simple machine wrapped around a cylinder?

• Lever

• Inclined plane

• Pulley

• Wheel and axle

What is the primary function of a worm gear?

• To increase speed

• To decrease speed and increase torque

• To change the direction of rotation

• To transmit power between parallel shafts

Which of the following is a characteristic of spur gears?

• They can transfer motion between non-parallel shafts.

• They produce a lot of noise at high speeds.

• They are primarily used to increase torque.

• They are used to change the direction of motion.

What advantage does a compound pulley system have over a single pulley system?

• It requires more effort to lift the load.

• It decreases the distance the effort travels.

• It increases the mechanical advantage.

• It is simpler to set up.
