QUESTION 2 Figure 2 shows a design of one gear train on shaft with 50mm in diameter. Gear W₁ and W2, is design to be located and supported between two rigid bearings at R₁ and R₂. While gear W3 and W₁ are designed to be overhang on shaft after bearing R₂. The design speed of shaft was limited to be operated below 5,000 RPM and the shaft was made from is stainless AISI 302 with a Young's modulus of 180 x 10 N/m². Ignore the self-weight of the shaft. a) b) c) d) Draw a free body diagram and determine the value of R1 and R2 and their direction. Draw the force and moment diagram then obtain the location of maximum bending moment. Using Macaulay's method for the deflection of beams, determine the defelction (y) at four points of pulleys W1, W2, W3 and W4. Determine the critical speed of the shaft, (RPM). Explain either the critical speed is safe compare to design speed. Justify your answer. L₁-0.15 m L₂-0.15 m O R₁ 130 N W₁ E 300 N W₂ L₂= 0.24 m Figure 2 L₁= 0.2 m R₂ 250N W3 100N WA
