Assume a motor running on A, B, and C balanced currents, and their magnitude is 10A. Find the corresponding d-axis quantity using “park’s” transformation if the d-axis leads the q-axis by 90 electrical degrees; the angle is between the q and a-axis. Here, the angle is 240 degrees, and the scaling factor of the d-axis is 23.

The top crossbar for a gantry crane is to be constructed out of 6 × 2.157 channel (see table below for geometric properties) and with a length L = 8 feet. The channel is implemented as shown in the close-up so that it can be considered as a simply-supported beam that bends about the 1-1 axis. It is desired that the crane be used to repeatedly lift a weight at the midpoint of the crossbar. Consider the weight as a point force acting through the centroid of the channel that varies between 0 lbf and 9,000 lbf. The channel material is hot-rolled AISI 1040 (Sut = 76 ksi, Sy = 42 ksi), and you don’t need to consider any stress concentrations or the weight of the channel crossbar. Determine the following: The maximum bending stress (σmax) in the crossbar (the shear stress can be ignored in the analysis) The modified endurance limit (Se) for this application with 95% reliability The factor of safety with respect to infinite life (nf) using the Modified Goodman criteria The number of cycles (N) it is expected to last before fatigue failure Write down all your work to scan and submit, including a free-body diagram and bending moment diagram for the crossbar. σmax = [stress] ksi (round answer to 1 decimal place)Se = [Se] ksi (round answer to 1 decimal place)nf = [nf] (round answer to 2 decimal places)N = [N] (round answer to nearest thousand; enter “infinite” if infinite life is predicted)

  LOB = 230 mm, LBC = 280 mm, LCA = 300 mm, dOB = 42 mm, dBC = 48 mm, dCA = 40 mm   The shaft (OA) is machined from 1045 cold-drawn steel (Sy = 530 MPa, Sut = 630 MPa) to the dimensions provided. The shaft rotates at constant speed of 1800 rpm and is supported by bearings at O and C. The belt tensions on pulleys A and B result in a constant torque on the shaft of 250 Nm and a completely reversing bending moment at critical point C of 500 Nm. The transition between diameters at point C has a fillet with a 2-mm radius. Determine the following: The modified endurance limit (Se) for this application with 95% reliability The factor of safety for first-cycle yielding (ny) The factor of safety with respect to infinite life (nf) using the Modified Goodman criteria Write down all your work to scan and submit. Se = [Se] MPa (round to 0 decimal places)ny = [ny] (round to 2 decimal places)nf = [nf] (round to 2 decimal places)
