Calculation of Limits using ANSI B4.1 Standard Tables, when one of the design Features Exists. When calculating the limit tolerances for features that mate with purchased parts, the purchased part size must be known. This may be obtained be requesting a drawing from a vendor or, a caliper or micrometer can be used to obtain an accurate size. A shaft diameter of 1.2500" is to be pressed into a part using a FN3 interference (force) fit. Limits of size for the shaft diameter are 1.2500" and 1.2495". Determine the Limits of the hole diameter. Show all work.

Multi part question The rotating shaft shown is subjected to a constant force. Shaft material is AISI 1020 cold drawn steel. The shaft was turned on a lathe using standard carbide tooling. No heat treatment of the shaft was performed. Assume 99% reliability based on material property data. Shaft dimensions are shown in the illustration below. All dimensions in mm. External force is 3.927 kN. Calculate the highest alternating stress in the shaft, in MPa. -20 -35 D. 180- -500 3R. -280- -175- -50 D. 25 D.

B) A simply supported shaft is shown in the following Figure. A constant magnitude distributed unit load p is applied as the shaft rotates. The shaft is also subject to a steady torque of Tmax 2000-N -m., find the diameter of shaft required to obtain a safety factor of 2.5 in fatigue loading if the shaft is steel of Sut 814 MPa and Sy 703 MPa. The dimensions are in cm, the distributed force in N/cm, and the torque is in N-m. No stress concentrations are present, the shaft is machined, the required reliability is 90%, and the shaft operates at room temperature Figure: 1= 20-cm: b = 18-cm ; a = 16 cm Applied distributed load p:= 1000 N em ; 区区
