Average Normal Stress | Statics

https://goo.gl/CD3T0c for more FREE video tutorials covering Engineering Mechanics (Statics & Dynamics) The objectives of this video are to discuss about average normal stress and to work out on average stress in members. At first, the video introduces with the equation of average normal stress clearing the concept that the average normal stresses are equal to the ratio of axial resultant forces & area of cross-section. Next, the video shows an exemplary column structure asking to draw the axial force diagram (AFD) & to work out on the average normal stress developed in the column. The diameter of the cross-section is given as 500 mm and the column is subjected to an axial load of 10 KN. Moving on, the video finds the support reaction of the column using the principle of equilibrium and subsequently calculates the axial force by making a critical cut at arbitrary section. Next, the video uses the obtained values to plot an axial force diagram & successively calculates the average normal stress giving input the required values into the respective equation of stress. Overall, the video tries give a brief inside to average normal stress and how to do the calculations of average normal stress.
