A platform is supported by a row of aluminum pipe columns having length L of 5 m and outer
diameter d of 300 mm. The bases of the columns are set in concrete footing and the tops are
supported by the platform laterally (like a hinge). The columns are being designed to support
compressive loads P of 200 kN. Determine the minimum required thickness t of the columns if a
factor of safety n = 1.5 is required with respect to Euler buckling. E = 72 GPa and ? y = 350 MPa.

Q. No 3. The pressure drop Dp over a length L of pipe is assumed to depend on the average velocity V, the pipe’s diameter D ,the average height h of the roughness elements of the pipe wall, the ﬂuid density ρ ,and the ﬂuid viscosity µ .Write a relationship between the pressure drop and the other variables. Use Indicial Method (Rayleigh’s Method) only.

A cylindrical aluminum pipe of length 1.42 m has an inner radius of 1.60 ×10-3 m and an outer radius of 3.39 ×10-3 m. The interior of the pipe is completely filled with copper. What is the resistance of this unit? (Hint: Imagine that the pipe is connected between the terminals of a battery and decide whether the aluminum and copper parts of the pipe are in series or in parallel.)

1. A rod of uniform density and weight W=120N has length L=1.00 m and is supported at two points, under the 10 cm point and under the 70 cm point. The support at 10 cm exerts a force NL on the rod and the support at 70 cm exerts a force NR on the rod, both forces being in the vertical direction. (a) Use the conditions of static equilibrium to find the values of NL and NR. (b) In order...
