A brass bar, having cross sectional area of 150mm˛, is subjected to axial force of 50kN. What will be the total strain of bar if E= 1.05 x 104 N/mm˛?
View Answer Explanation
A composite bar of two sections of each of length 100mm, 150mm. When force is applied, all the sections causes an elongation of 0.1mm. What will the resultant strain in the bar?
If the given forces P?, P?, P?, P?,and P? which are co planar and concurrent are such that the force polygon does not close, then the system will
