A simply supported shaft is shown in the figure below. P - w, L= gear key A constant-magnitude transverse load P = 750 lb is applied as the shaft rotates subject to a time-varying torque that varies from Tmin=-200 lb-in to Tmax=400 lb-in. Assume the following data: a = 4 in, b = 12 in, l = 14 in. Assume a st diameter of 1.75 in. The shaft is steel of Sut = 108 kpsi and Sy = 62 kpsi. The key is steel of Sut = 88 kpsi and Sy = 52 kpsi. The surface is machined, reliability is 90%, the shaft operates at a room temperature.

The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600 rpm and is supported in rolling bearings at A and B. The applied forces are F₁ = 1600 lbf and F2 = 640 lbf. A steady torque of 1600 lbf-in is being transmitted through the shaft between the points of application of the forces. 1 / in ] A in [lin -10 in- F₁ in F₂ -10 in- All fillets in R. 12in] 3 in The value of the notch sensitivity is The value of the fatigue stress concentration factor is in NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the value of the theoretical stress concentration factor for torsion, the notch sensitivity, and the fatigue stress concentration factor? (You must provide an answer before moving to the next part.) The value of the theoretical stress concentration factor for torsion is

What are the maximum, minimum, and average power values for the shaft shown in the figure below if the shaft speed is 50 rpm, l = 14 cm, a = 4 cm, b = 12 cm, P = 750 N, Tmin = -200 N-m, Tmax = 400 N-m.

Hi, I need help with this question.

A motor is used to drive a gear assembly at 200 rpm. The main gear is in the center of a 1 m long (0.5 m to the left and right of the gear) 50 mm diameter solid circular shaft, and power is taken from the two shaft ends. 25 kW is taken on the left end and an unknown amount of power is taken at the right end. the torque to the left side of the gear is? maximum shear stress to left of gear? If the maximum shear stress on the shaft to the right of the gear is 125 MPa, approximately how much power is being drawn off from the right side of the shaft? The shaft can be made from 6061-T6 aluminum. It has adequate strength to withstand the loading conditions in the scenario, including the loading on the right side of the shaft. true or false?

pls expalin to me step by step and write clearly. i will rate your answer immediately  thanks

A solid steel [G= 12900 ksi] shaft with the diameter of d = 1.375 in. is subjected to torques TB = 250 lb.ft, TC = 300 lb.ft, and TD = 140 lb.ft, acting in the directions shown in the figure. Assume a = 48 in., b = 74 in., and c = 40 in. Determine the rotation angle of pulley C with respect to the support at A. In rad

In a gear set, a 36-tooth spur pinion drives a 60-tooth spur gear. The teeth of these gear are cast iron profile. The diametral pitch is 6-teeth/in, the face width si 0.5 inches, and the pressure angle is 20 degrees. Assume that the pinion transmits 10 hp at a speed of 2000 rpm. Find the tangential load in lbf Find the contact stress in kpsi, assuming CP=1960 psi.
