This is correct. You've calculated the maximum load.dblanche said:I have used every formula that I can think of, I've used the following equations:
Stress= Force / Area
470 x 10E06 = force / 5.03 x 10E-05
Force = 23624.78 N
There's a small error here. Should the allowable load be 5 times the maximum load ? What happens to the rod if you apply a load greater than the maximum load ?then multiply 23624.78 by the factor of safety being 5
= 118123.9 Newtons?
Stress is the force applied to an object, while strain is the resulting deformation or change in shape of the object.
Stress and strain can cause materials to deform, break, or fail depending on their strength and elasticity. Too much stress can exceed a material's strength and cause it to break, while too much strain can cause permanent deformation.
The three main types of stress are tensile, compressive, and shear stress. Tensile stress stretches or elongates a material, compressive stress squeezes or shortens it, and shear stress causes one part of a material to slide past another. Similarly, the three types of strain are tensile, compressive, and shear strain, corresponding to the different types of stress.
Stress is typically measured in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m2). Strain is measured as a percentage or decimal of the original length or size of a material. Engineers and scientists use specialized instruments like strain gauges and extensometers to accurately measure stress and strain.
Stress and strain can occur in everyday life through activities like lifting heavy objects, bending or stretching materials, or even just walking. Other causes include temperature changes, pressure, and impact or vibration. Additionally, stress and strain can build up over time due to repetitive actions or environmental factors.
