Read the paragraph below and answer the question that follows.
"The helical gears are similar to spur gears but have angled teeth. This helical tooth arrangement enables smoother and quicker operation compared to spur gears. Helical gears are commonly used in applications where high torque transmission and reduced noise are essential."
Write any two key differences between helical gears and spur gears.

Answer

Two key differences between helical gears and spur gears are:

Tooth arrangement — Helical gears have angled (inclined) teeth, whereas spur gears have straight teeth.
Operation and noise — Helical gears operate more smoothly and quietly due to gradual tooth contact, while spur gears produce more noise because the teeth engage suddenly.
