The end of a uniform bar of length L = 8 m, weight is supported by a cable which makes an angle θ = 37 ° with the bar. The other end rests against the wall, where it is held by friction, as shown in the figure. The coefficient of static friction between the wall and the bar is μe = 0.50. Determine the minimum distance x from point A where an additional weight (the same as the weight of...

Crew members of a submarine attempt to escape an accident 100
meters below the surface. Consider that the density of seawater is
1030kg / m3 whose atmospheric pressure has a value of 1.01.105 Pa.
Knowing that, in the submarine, there is an emergency exit door
with an area of 0.6m2, the approximate force that must be applied
to this door to open it at this depth is worth in newtons:
