What is the difference between tension and pressure, and how do they relate to each other in terms of their effects on materials?

Tension is a pulling force that stretches or elongates a material, while pressure is a pushing force that compresses or squeezes a material. Tension and pressure are related in that they both cause stress on materials, but in different ways. Tension tends to cause materials to elongate or deform, while pressure tends to cause materials to compress or buckle. Both tension and pressure can lead to structural failure if the material cannot withstand the forces applied.
