The net of the two opposite forces is zero, but that doesn't mean these forces disappear individually. All you can infer is that because the net force is zero, the body remains in static equilibrium. Internally within the body, the forces are still acting to pull apart or push together the structure of the material from which the body is composed.Arceus74 said:We know that when two equal forces act in opposite direction they nullify each other.
But when two equal forces act on a body yet it deforms eventhough the resultant force is zero?
Can you explain how the stress is created and results in longitudinal strain?
It depends. The type of load applied to a body and where it is applied on the body influence the nature of the stress.Arceus74 said:How are those internal forces generated?
Stress can be caused by a variety of factors, including external events or situations, such as work pressure or financial problems, as well as internal factors, like negative thoughts or perfectionism. Everyone experiences stress differently, so what may cause stress for one person may not be the same for another.
When we experience stress, our body goes into "fight or flight" mode, releasing hormones like cortisol and adrenaline. These hormones increase heart rate, blood pressure, and breathing, preparing our body to respond to the perceived threat. However, prolonged exposure to stress can lead to negative effects on our physical and mental health, such as headaches, digestive issues, anxiety, and depression.
In small doses, stress can actually be beneficial as it can motivate us to take action and improve our performance. This is known as "eustress" or positive stress. However, when stress becomes chronic and overwhelming, it can have detrimental effects on our well-being.
There are many ways to manage stress, and what works for one person may not work for another. Some common strategies include exercise, mindfulness practices, talking to a trusted friend or therapist, and setting boundaries and priorities. It's important to find healthy coping mechanisms and to make self-care a priority when dealing with stress.
Yes, genetics can influence how we handle stress. Some people may be more genetically predisposed to experience anxiety and stress, while others may have a higher resilience to stress. However, environmental and lifestyle factors also play a significant role in how we respond to stress.
