A horizontal bar is used to hold an object of m kg between two walls, as shown in the figure. The equally exerted forces of the bar against the walls can be changed by adjusting the length from the bar. The system is only sustained by friction between the ends of the bar and the walls. The coefficient Static friction between these two is ms. Find the value of the forces F that guarantee the equilibrium of the system.

Neglecting the weight of the bar of length L, pivoted at its
center and balanced with a block of weight W at a distance x from
the left side, at the beginning and at the end of the bar are two
charged spheres q and 2q respectively.
At a distance h directly below the spheres are other charged
spheres Q.
Find the distance x when the bar is balanced in the position
shown.
What value must h have so that...

A horizontal bar is used to support a kg object between two
walls, as shown in The figure. The equally exerted forces of the
bar against the walls can be changed by adjusting the length from
the bar. Just enough friction to the system between the ends of the
bar and the walls. The coefficient Static friction between these
two is ms. Find the value of the forces F that guarantees the
equilibrium of the system.
Calculate the normal force in A in the bar and pulley system
shown. In O there is a "pin". Assume that the surface at A is
smooth or smooth. The mass value of the cylinder (m1) is equal to
20 kg. Evaluate the normal force at A for values of m1 (cylinder
mass) from 10kg to 60kg at intervals of 10 (6 cases). Make a graph
of Normal vs. cylinder mass (Normal in y / Mass in x). It is...
Question Translation:
On a car of mass M, two forces act as shown in the figure
above. Find an expression for the acceleration of the car in terms
of T, F, and M. What happens to the acceleration if we double the
mass of the car?
An object of mass M is in free fall (the only force on the
object is its weight). Make a force diagram for this case. Use
Newton's second law to calculate the acceleration of...

Two parallel conductor rails with negligible resistance are
connected at one end by a resistance resistor R=1.40 Ω, as shown in
the figure. The rails are placed in an upwardly directed magnetic
field B= 5.00 T , which is perpendicular to the plane of the rails.
This magnetic field is uniform and independent of time. The
distance between the rails is l= 0.20 m. A conductor bar slides
without friction on the top of the two rails at a constant...
