Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

For two existing torques, what third force at a given distance from the pivot will balance them? Imagine a meter stick set up as in the figure. It hangs from a central bracket, and two hanging masses can hang from it from each of their brackets. At a third location, a force probe can either pull up or pull down on the stick, depending on what is needed to balance the stick. The mass of the meter stick is 120 g. sketch the situation (drawing r1, r2, r3, F1, F2, and F3) and determine the magnitude (value) and direction (+ or -) of each torque. Don't include the mass of a bracket that would hold the hanging mass in place; assume the mass listed is the entire mass hanging at that point. For each trial, use the principle of equilibrium (where the sum of torques is zero) to calculate the third, unknown force acting at x3
The shaft shown in the figure is machined from AISI 1040 CD steel. The shaft rotates at 1600 rpm and is supported in rolling bearings at A and B. The applied forces are F₁ = 1600 lbf and F2 = 640 lbf. A steady torque of 1600 lbf-in is being transmitted through the shaft between the points of application of the forces. 1 / in ] A in [lin -10 in- F₁ in F₂ -10 in- All fillets in R. 12in] 3 in The value of the notch sensitivity is The value of the fatigue stress concentration factor is in NOTE: This is a multi-part question.

I tried this problem the only way I can think of and I don't know what I could be missing it would be really helpfull if you could show me what I am misssing in my calculations
The picture shows the rear swivel axle bearing design of a 4-wheel wagon. It is known that the speed of the wagon wheels is n = 37 rpm. The total radial load carried by the wagon is given as Fr= 16060 Newtons. In addition, due to road conditions, Fa axial load is applied to the wagon. If the axial load on the A bearing is 10% of the radial (vertical) load on this bearing, calculate the dynamic load number (C) of the bearing in the A bearing in Newtons for 18616 hours of life. fo*Fa/Co = 0.345 Pi=3.14
