An axle is composed of elements laid by S355 E-module 2.1x105 N/mm2, transverse contraction factor 0.3. As shown in the picture, we have on the right side two forces of 10,000 N whichshows at an angle 15 upwards and forms a moment which is statically compensated by the force F2 on the left side. The shaft is stored in positions A and B. In the same position (for the sake of simplicity) there are two critical cross-sections that lead to stress concentrations.v) Determine b nom which is necessary to transfer the torque you have calculated when the coefficient of friction is 0.3. Comment on the result when you compare b real and b nom.vi) Determine G max.vii) Does the sleeve withstand the stresses when the permissible stress is 355 N/mm2?

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
