Answer 1

Answer:

Halved

Explanation:

Answer 2

Halved

If the module of a spur gear is reduced to half the bending stress of the gear will be Halved.

• Increase and redesign the gear in order to lessen contact stress in the gear module. The gear material's lower than surface endurance limit is being reached by the contact stresses.
• Gears are subject to two main forms of stresses: contact stresses from repetitive impact, or sustained contact, of one tooth surface against another, and bending stress from the transmitted load at the root of the teeth.
• Bearing stresses are the strains created when two elastic bodies are pressed together. Due to the limited contact areas, they are confined to a tiny area on the material's surface and may be very high.
• When an object is subjected to a heavy load at a specific spot, it often experiences bending stress, which causes the object to bend and tyre. When using industrial machinery, as well as when concrete and steel constructions are put under a tensile force, bending stress can develop.
