Step 1
The shaft is supported at points A and D. There are two downward forces of 2.4 kN (2400 N) at points B and C. The distance from A to B is 0.15 m. The distance from B to C is 0.30 m. The distance from C to D is 0.15 m. The total length of the shaft is $0.15 + 0.30 Show more…

1. The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by a gear ( not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the driver gear acts at a pressure angle of 20 degree. The shaft transmits a torque to point A of TA =340 N.m. The shaft is machined from steel with d=0.043m, Sy=420 MPa Sut=560 MPa , Kf=2.4, and Kfs=2.1. The maximum bending moment Ma will be at point C. Consider Mm and Ta are zero. Calculate F, Ma, Tm, von Mises maximum stress and Ny (safety factor).
