A gear tooth with a larger pressure angle is considered to be:

A gear tooth with a larger pressure angle is considered to be stronger due to the increased tooth depth and the geometry that enhances its resistance to forces acting on the teeth during operation. A higher pressure angle results in a more robust tooth profile, which can better withstand heavy loads and reduce the risk of tooth failure during transmission.

The larger pressure angle also affects how the forces are distributed across the gear teeth, which can lead to improved performance in high-load applications. This design feature helps accommodate higher torque and can reduce wear, making the gears more durable over time.

While some options relate to other aspects of gear design, they do not capture the strength relationship as accurately as the correct choice. The option discussing weaker attributes relates to considerations outside of loading capacity, and the mention of machining inaccuracies or helical gear applications do not inherently reflect the conversation around pressure angles directly related to tooth strength.
