Question
The shaft is supported at its ends by two bearings $A$ and $B$ and is subjected to the forces applied to the pulleys fixed to the shaft. Determine the resultant internal loadings acting on the cross section at point $D$. The 400 -N forces act in the $-z$ direction and the 200 -N and 80 -N forces act in the $+y$ direction. The journal bearings at $A$ and $B$ exert only $y$ and $z$ components of force on the shaft.
Step 1
This gives us the equation: \[ \sum M_{B_y} = 0 \] which simplifies to: \[ -A_y \times 1.4 + 400 \times 0.7 + 116 \times 0.4 = 0 \] Solving this equation gives us the value of \(A_y = 245.714 \, \text{N}\). Show more…

The shaft is supported at its ends by two bearings $A$ and $B$ and is subjected to the forces applied to the pulleys fixed to the shaft. Determine the resultant internal loadings acting on the cross section located at point $C$. The 300 -N forces act in the $-z$ direction and the 500 -N forces act in the $+x$ direction. The journal bearings at $A$ and $B$ exert only $x$ and $z$ components of force on the shaft.
The shaft is supported by a journal bearing at $A$ and a thrust bearing at $B$. Determine the normal force, shear force, and moment at a section passing through (a) point $C$ which is just to the right of the bearing at $A,$ and (b) point $D$ which is just to the left of the 3000 -lb force.
