The pedal system shown in the figure is exerted by both an up and down mechanism. These forces are Fmax=350*SN/10 N, Fmin=-150*SN/10 N. It is desired that h/b = 5 seen in the figure. This piece is AISI 1040 and has a maximum tensile stress of 670Mpa and a yield stress of 540Mpa. Known weakening factors are known as kb=ky=kd=0.8. The notch factor for all stresses is assumed to be Kç=1.5. It is desired to last up to its minimum indefinite life at the cross-section measurement point (bxh) shown in the figure. According to Goodman theory, what should be the minimum size (b and h value) of this section in order to meet this condition. SN=89

The shaft is subjected to a downward uniform distributed load q 50 lbf/in over 1/3 of the span, centered around the mid-span, in the region x=L/3 to x=2L/3. Downward means in the negative y-direction. Also, torque T = 4000 lbf.in and axial force N = 2000 lbf are applied at x=L. = N Draw the shear and bending moment diagrams, and using that, calculate at x = L/2, y = D/2: • The normal stress , which is the sum of the axial stress N/A plus the bending stress -yM/I. • The shear stress due to shear V. • The shear stress due to torque T. • Draw Mohr's circle 2D and from it calculate the max. shear stress.

2. Two shafts, one solid the other one hollow, are connected end to end by means of a coupling in which there are 8 screws on the pitch diameter D = 250 mm. The solid shaft has diameter d = 50 mm and transfers the power P = 500 kW at 75 rev/s. The external diameter of the hollow shaft is dex = 75 mm. %3D Note: All parts of the system must be equally strong, and able to transfer the required power Calculate: (a) The internal diameter d; of the hollow shaft (b) The diameter of the bolts d, connecting the two shafts (c) If the hollow shaft has to be replaced by a rectangular hollow cross-section with outer dimensions b xh and uniform wall thickness of 4 mm. Calculate the values b, h while following the request to keep h = 2b
A shaft/hub connection transmits a torque C =60N.m. We use a rectangular key (W=14mm x H=9mm) with a length of 30mm for a 45mm diameter shaft. Calculate the force exerted on the key.Calculate the compressive and shear stress.
A line shaft supporting two pulleys A and B is shown in figure below. Power is supplied to the shaft by means of a vertical belt on the pulley A, which is then transmitted to the pulley B carrying a horizontal belt. The ratio of belt tension on tight and loose sides is 3:1. The limiting value of tension in the belts is 2.7 kN. The shaft is made of plain carbon steel 40C8 (Sut = 650 N/mm2 and Syt = 380 N/mm2). The pulleys are keyed to the shaft. Determine the diameter of the shaft if, k = 1.5 and k, = 1.0. (Sm valing odi of 450 A B 2500 22.0=1821 P3 4500 250 ₁ 4500 P1 A P₂ P4

A simple diagram of a driveshaft ABC is shown in Figure 3. The power generated by an engine is transmitted via the drive shaft, ABC. The section AB is a solid circular shaft 0.7 m long and the section BC is a hollow circular shaft 1.0 m long with 110 mm outer diameter and 55 mm inner diameter.
