The rotating stepped shaft in the figure is produced from 85080M30 steel by machining method. It works at ambient temperature. If the force applied to the shaft is given as P=10 kN as constant, calculate the diameter d for the shaft to have an infinite life.(f=0.9) (Sut=600MPa)

The steel hollow shaft is rigidly attached to a solid bronze shaft by a bolt coupling. A maximum torque T can be applied to the ends of the shaft without failure. Use G = 83 GPa for steel and G = 35 GPa for bronze. 100 mm 70 mm 70 mm 1.5 m 2 m

A solid 2.1 in. diameter shaft is used to synchronize multiple mechanisms in a manufacturing plant. The torque delivered by the shaft is 3200 Ib-in. What horsepower must be delivered to the shaft to maintain a shaft speed of 690 rpm? What is the maximum shear stress developed in the shaft? Answer: P = hp T= psi

Question 4: A machine of 540 kg is bolted at the middle of two parallel simply supported steel beams. The clear span of the beam is 2.4 m. The moment of inertia of the cross-section of each beam is I = 4.2×10¯6 mª. The Young's modulus of the steel is E 200 GPa. When the machine is operating, it will generate a vertical force P(t)=Posinot. When the machine runs at 300 rpm, Po= 1500 N. Neglect the weight of the beams and assume 2% viscous damping in the system. Determine the amplitude of steady-state deflection of the beams at their midpoint when the machine runs at 300 rpm. machine 1.2 m = 1.2 m Steel beams

A bar is shown in figure below: 200 kN 50 mm Id mm 50 mm 200 kN Lmm- Lmm Lmm 500 mm The bar is subjected to a tensile force of 200 kN at each end. The stress in the middle portion is limited to 150 N/mm². If the total elongation of the bar is limited to 0.30 mm, then the value of (L1 + L2) will be [Take E= 200 kN/mm²]

A compound shaft consisting of a bronze segment and an aluminum segment is acted upon by two torques as shown in figure 2. Solve to determine the uniform shaft diameter subject to the following conditions: tbr < 80 MPa, Tal < 55 MPa and the angle of rotation of the free end is limited to 6°. For Bronze, G = 35 GPa and for aluminum, G = 28 GPa.

Determine the reactions at the supports. Assume the support at A is fixed and that at B is a roller. Take E = 29x103 ksi. The Moment of inertia of each segment is shown in the figure. (By Using The Force Method) A 9 ft- IAB 30 k = 600 in 18 ft B 30 k IBC= 300 in | C 12 ft-

1) The head H is connected to the cylinder of a compressor using six steel bolts. If the clamping force in each bolt is 4000N, determine the normal strain in the bolts. Each bolt has a diameter of 5 mm. If o₂ = 280 MPa and Est = 210GPa, what is the strain in each bolt when the nut is unscrewed so that the clamping force is released? a) 0.970 b) 0.203 c) 0.970(10-³) d) Insufficient information to determine because the stress is beyond yield point H &
