For the following questions answer them individually
There is a free overall fall at the end of a long channel. For a given flow rate, the critical depth is less than normal depth What gradually varied flow profile will occur in the channel for the flow rate?
For an isotropic material, the relationship between Young’s Modulus(E), Shear Modulus(G), and Poission’s ratio $$(\mu)$$ is given by
A rod of length L= 500 mm and cross sectional area A = 60 $$mm^{2}$$ is made of an elasto plastic material having a modular of elasticity E = 200 Gpa nits elastic range and yield point $$\sigma y$$=300 Mpa. The rod is subjected to an axial load until it is stretched 7 mm and the load is then removed. What is the resulting permanent set?
The changein the volumeper Unit volume occurs when normalstresses are applied on an element of isotropic materialis called as
Determinethe change in volumeofa steel block of size $$80mm \times 40mm \times 60mm$$ when it is subjected to the hydrostatic pressure P = 180 Mpa. Use E = 200 Gpa and v = 0.29
