Define each of the stress types: Stress

Compression

Tension

Shearing

a.

b.

c.

d.

Explanation:

STRESS : A state of mental or emotional strain or tension resulting from adverse or very demanding circumstances.

COMPRESSION : If a cylinder is compressed under the action of the applied force, the restoring force per unit area is known as the compressive stress.

TENSION : Mental or emotional strain. OR The state of being stretched tight.

SHEARING : A deformation of a material substance in which parallel internal surfaces slide past one another.

BRAINLEST PLEASE

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

i got you i did it ya know what it is just needing to fill this in for a quick task!
