Chapter 7, Problem 7P

For the problem specified in the table, build upon the results of the original problem to obtain a preliminary design of the shaft by performing the following tasks.

(a)    Sketch a general shaft layout, including means to locate the components and to transmit the torque. Estimates for the component widths are acceptable at this point.

(b)    Specify a suitable material for the shaft.

(c)    Determine critical diameters of the shaft based on infinite fatigue life with a design factor of 1.5. Check for yielding.

(d)    Make any other dimensional decisions necessary to specify all diameters and axial dimensions. Sketch the shaft to scale, showing all proposed dimensions.

(e)    Check the deflections at the gears, and the slopes at the gears and the bearings for satisfaction of the recommended limits in Table 7–2. Assume the deflections for any pulleys are not likely to be critical. If any of the deflections exceed the recommended limits, make appropriate changes to bring them all within the limits.

Design of a Shaft subjected to Alternating Loads 1. [Proof of Concept] Considéra machined steel circular shaft subjected to maximum and minimum bending moment of 1000 and 4000 lb .in, respectively; and a maximum and minimum torque of 250 and 1600 Ib.in, respectively. Consider the factor of safety to be 2, the yield strength of the materials 40 ksi, and its ultimate strength to be 70ksi.Determine the minimum diameter of the shaft for the case where D is 20% larger than d, the fillet radius is 10% of d, and reliability is 99%. You may use DE-ASM E formula. 2. Write a computer code that can take Tm, Ta, Mm, Ma, choice of material, safety factor, and other necessary assumptions from the user and return an estimated diameter for the shaft.Choice of inputs is up to you. Note that many of the required quantities are themselves function of the shaft diameter. Your code should be submitted with a report.
Bearing stress 5. Please provide proper discussion and illustration also complete solution and clear solution please thank you A solid shaft is designed to transmit 50kN @ 1800 rpm to a gear by means of 156 mm long key with square cross-section. The shaft diameter is 35.6mm. What should the cross-section be in mm2 to resist shearing, if the allowable shear stress on the key is 20 MPa?
(5) A 76mm solid shaft is to be replaced with a hollow shaft of the same torsional strength. Determine the inside diameter and the percentage weight savings if the outside diameter of the hollow shaft is 100mm.
