A 22 kg compressor impeller wheel is driven by a 13 kg turbine mounted on a common steel shaft, as shown in Figure 1 below. E =207 GPa. Assuming the bearings to be stiff and acting as supports. Calculate: a) The reactions of the supports at A and C [4] b) The shaft deflection at B and D using Macaulay’s method. [11

Repeat Problem 11.3-9. Use two C 150 × 12.2 steel shapes and assume that E = 205 GPa and L = 6 m.

Compare the angle of twist 1 for a thin-walled circular tube (see figure) calculated from the approximate theory for thin-walled bars with the angle of twist 2 calculated from the exact theory of torsion for circular bars, Express the ratio 12terms of the non-dimensional ratio ß = r/t. Calculate the ratio of angles of twist for ß = 5, 10, and 20. What conclusion about the accuracy of the approximate theory do you draw from these results?

A tubular shaft being designed for use on a construction site must transmit 120 kW at 1,75 Hz, The inside diameter of the shaft is to be one-half of the outside diameter. If the allowable shear stress in the shaft is 45 MPa, what is the minimum required outside diameter d?

Determination of vertical displacement of Mid-Term Project pipe assembly Find the vertical displacement at position C in the figure. 800 mm Pipe inner diameter: 40 mm, Pipe outer diameter: 60 mm Material: A-36 Steel 600 N B. -By the force 600N, the AB part of the pipe is subjected to bending and torsional loads. BC part is subjected to bending load. -The energy equation by this load is as follows. Energy equation by torsional load: 400 mm T²dx (U), = 2GJ Problem: Energy equation by bending load a) First, draw a free body diagram and the AB part Of the bending/torsional load of the BC and Derive the bending load equation. So M²dx (U) = 2EI By applying it to the high energy formula, Save energy and make it the same as external energy Release to find the vertical displacement. -The sum of the internal energy of 2 energy is as follows. U=U: +Ub b) Creo modeling and structural analysis -Due to energy conservation, the sum of the internal energy U is the external due to the load 600 NGet the…
