QI: A double-threaded 30-mm power screw is 30 mm in diameter with a pitch of 6 mm. The coefficients of friction are 0.05 for the collar and 0.08 for the threads. The frictional diameter of the collar is 40 mm. if Tg=18 N.m: 1- Find the A vertical load on the screw, the torque used to lower the load and screw efficiency. 2- Compute all the stresses on the screw body that will cause by the load.
2. A 30-mm bolt with an initial tension of 35 kN is subjected to several types of stresses during initial tightening or due to screwing up forces. If the bolt has a core diameter of 25.7 mm and considering 5 threads are already engaged with the nut, calculate the shear stress across the thread and the crushing stress between the threads. Assume 3.5 mm as the width of the thread section at the root.
A part is loaded with a combination of bending, axial, and torsion such that the following stresses are created at a particular location:Bending: Completely reversed, with a maximum stress of 60 MPaAxial: Constant stress of 20 MPaTorsion: Repeated load, varying from 0 MPa to 70 MPaAssume the varying stresses are in phase with each other. The part contains a notch such that Kf,bending = 1.4, Kf,axial = 1.1, and Kf,torsion = 2.0. The material properties are Sy = 300 MPa and Su = 400 MPa. The completely adjusted endurance limit is found to be Se = 160 MPa. Find the factor of safety for fatigue based on infinite life, using the Goodman criteria. If the life is not infinite, estimate the number of cycles, using the Walker criterion to find the equivalent completely reversed stress. Be sure to check for yielding.
