what is the mathematical equation for stress?
310646
The stress equation is σ = F/A . F denotes the force acting on a body and A denotes the area. Units of stress are the same as units of pressure - Pascals (symbol: Pa) or Newtons per squared meter.

Stress is a force acting on a rock per unit area. ... Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.

To calculate the tension of a string in pounds use the formula below, inserting the three variables described above: T (Tension) = (UW x (2 x L x F)2) / 386.4 To convert the result into Newtons, simply multiply by 4.45. If you know what tension you want the string to have, you can calculate the string unit weight.

Normal stress is a result of load applied perpendicular to a member. Shear stress however results when a load is applied parallel to an area. ... Like in bending stress, shear stress will vary across the cross sectional area.

Stress is the force applied to a material, divided by the material's cross-sectional area. Strain is the deformation or displacement of material that results from an applied stress.

The causes of stress are coined as stressors. This occurs in two forms: external and internal. External stressors include major life events such as job loss, loss of a loved one or demands placed by the physical environment such as the excessive lighting or noise. Internal stressors occur within us.

Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate. Multiple Variables: It is possible to have experiments in which you have multiple variables.

The force equation will be T2-T1=Δma where 'a' is the acceleration of the tiny bit of the string . Now since Δm=0 ∴ T2=T1 i.e tension on either side of any arbitrary mass of the string is zero.In other words tension throughout the string is constant.

Engineering stress is when we calculate stress taking the cross-sectional area of the bar before it is loaded. True stress is when we calculate stress taking the current cross-sectional area of the bar as it extends due to the load. Both of them differ only in the choice of cross-sectional area.

Pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.
