What is meant by compressive and tensile stress?

Compressive stress is when a force is applied to an object, pushing it together. Tensile stress is when a force is applied to an object, pulling it apart.

When a force is applied to an object, it can cause stress, which is the internal force that resists the applied force. There are two types of stress: compressive and tensile stress. Compressive stress occurs when a force is applied to an object, pushing it together. This can cause the object to become shorter and wider. Tensile stress occurs when a force is applied to an object, pulling it apart. This can cause the object to become longer and narrower.

The amount of stress an object can withstand before it breaks is called its strength. The strength of an object depends on its material properties, such as its elasticity and ductility. Elastic materials can withstand a lot of stress before they break, while ductile materials can stretch and deform before they break.

In engineering, it is important to consider the stress an object will experience in order to design structures that are safe and reliable. Engineers use stress analysis to determine the amount of stress an object will experience under different conditions. This allows them to design structures that can withstand the expected stresses and avoid failure.
