Briefly discuss the importance of Structural Mechanics in Mechanical Engineering? List four different types of loadings that can be applied on mechanical structures or components
Draw the vectors starting at the appropriate black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.
Carefully draw and label the hydraulic grade line - Determine the total system head for the pipe configuration below (Figure 1) when the rate of flow is 20 L/s and the total static head on the pump is 100 m.
Using a centrifugal pump, and a flow rate of 60 gal/min, calculate the break hp of the pump using water with a density of 62.4lbm/ft3 and do the same for a nonviscous liquid having a density of 0.85g/cm3.
Consider an incompressible 2D velocity field where u =-2xy and y = x^2-y^2 in Cartesian coordinates. Is it a valid 2D flow (satisfy the continuity equation)?
