Stress that occurs when forces act to stretch an object.
The concept of instinct in motivation theory was replaced by the concept of drive theory. Drive theory suggests that internal physiological needs create a state of tension or arousal that motivates individuals to act in ways that reduce this tension and restore homeostasis.
drive reduction theory
It's the tension of the strings in Superstring Theory. The tension refers to the ability of a string to vibrate at high or low frequencies, which is responsible for the energies of particles.
The cohesion-tension theory explains how water is moved from roots to leaves in plants. This theory suggests that water is pulled up through the plant by the cohesive forces between water molecules and the tension generated by transpiration in the leaves. This creates a continuous water column that is pulled up through the xylem.
The drive theory and the homeostasis theory suggest that needs create a state of tension within an organism, prompting behavior to alleviate that tension. According to drive theory, unmet needs lead to physiological drives that motivate individuals to engage in behaviors aimed at restoring balance. Similarly, homeostasis theory posits that organisms seek to maintain internal stability, and any deviation from this equilibrium creates a drive to act in ways that return them to a calm resting state. Both frameworks emphasize the role of motivation in reducing tension and achieving psychological and physiological balance.
The conflict theory explains capitalism, and how capitalism will eventually be demolished by the rise of the working class (causing tension/conflict)
In music theory, a 7th is an interval that spans seven notes in a scale. It is commonly used in chords to add color and tension to the harmony.
The cognitive dissonance theory suggests that when individuals experience inconsistency between their beliefs or attitudes and their behaviors, psychological tension arises. This leads to efforts to reduce this dissonance through attitude change, justification, or rationalization of their actions.
Tritone resolution in music theory creates tension by using a specific interval that sounds unstable. This dissonance is then resolved by moving the notes to a more stable interval, creating a sense of resolution and harmony in the music.
For ductile materials, teh VonMises theory is used; it combines tension and shear stresses in a different way than principal stress, which is used for brittle materials. In either case, its value is compared to the normal (tension/compression) stress allowable for the particular material.
The rise of water in plants is most satisfactorily explained by the cohesion-tension theory. This theory suggests that water evaporating from leaves creates tension that pulls more water up through the plant's vascular system. Additionally, cohesion between water molecules helps the water move in a continuous column.
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
